Mechanical Engineering Projects Ideas

Mechanical engineering is one of the oldest fields of engineering. Mechanical Engineering has played a very vital role in today’s modern and technologically developed world. Mechanical engineering has also spread its branches into electrical engineering. Electrical Engineering and mechanical engineering together introduced another interesting field called mechatronics engineering. Many mechanical engineering final year students search for project ideas on the internet. Therefore, I have compiled this project list for mechanical engineering students.

List of Mechanical Projects Ideas

Here is a list of mechanical project ideas with details of each:

Design and Fabrication of Mechanical Sprayer

The main idea behind the project was to design and build a sprayer that can be used for spraying water/medicine on crops. The current method for spraying involves the use of a tractor for large farms, while for smaller farms, the spraying is done manually by using labor. The original plan was to build a vehicle that is able to maneuver in farmed land while having a sprayer arrangement attached to it. The vehicle would utilize a much smaller engine (125 cc) than that of a tractor and hence be able to spray. The project will consist of the build container, the pump, as well as the PVC pipes with nozzles attached. This will be set up on a platform that can be pulled through a farm by attaching any vehicle. The platform will be designed to allow easy attachment. This is a very optimistic project for mechanical engineering final year students.

A Mini Robot to Operate in Unreachable Rough Terrains

This is a robotics related project for mechanical engineering students. The capability of accessing rough, rugged terrains and inaccessible zones can save lives in many rescue and relief situations. A few examples are entry into an earthquake-collapsed building, approaching those trapped in a building that is on fire, accessing damaged coal mines, and diffusing explosives in a rocky battlefield. Operation in hazardous environments such as chemical pipelines or nuclear zones is another application. The design project involves the design, analysis, fabrication, and control of a multi-terrain unmanned ground vehicle (MT UGV). The terrains encountered can be shallow mud, dry sand, tight spaces, etc., and the vehicle is expected to carry out surveillance through a camera or perform similar tasks. Importantly, it is lightweight, packable in size, and can be controlled flexibly, even with Android platform smartphones. The design project targets superior tread-climbing functionality (size-to-tread ratio) while retaining stability. It involves rigorous application of Machine Design, Linkage Dynamics, and Computer-aided Engineering.

Design, Analysis, and Fabrication of Spiral Axis Wind Turbine based on Archimedes Screw

Energy Crisis is one of the big issues our country is facing today. Due to the high and fluctuating increase in oil prices, the trend for energy generation has shifted towards renewable energy resources. Our main aim is to extract kinetic energy from wind by using the Spiral-axis wind turbine. While there are lots of horizontal and vertical-axis wind turbines installed in coastal areas of Pakistan, there is a need to design a wind turbine that can be installed in other urban and rural areas of Pakistan. Moreover, the noise produced by wind turbines is so high that they need to be installed far away from populated areas to reduce their effect on people. We are designing a Spiral-axis wind turbine with the ability to produce 250 Watts of power at an optimum wind speed. The spatial spiral blade figure creates a difference in pressure, resulting in better performance. The efficiency of the Spiral-axis wind turbine is greater than all horizontal and vertical-axis wind turbines with similar dimensions. This project is very crucial for mechanical engineering students in Pakistan.

Design and development of Solar Batch Collector (Solar Geyser)

Energy crisis is one of the major issues which the whole world is facing today. Because of this energy crisis, different research and development projects are in progress, focusing on utilizing non-renewable sources to meet the day-to-day energy needs. In this regard, our project in mechanical engineering focuses on utilizing available solar radiation to provide hot water for domestic use.

This project investigates the thermal performance of a unique type of solar geyser, the solar batch collector. The selected type of solar geyser provides high outlet temperature since the absorber area is much larger. The solar batch collector has three insulated sides, with glazing at the top which transfers solar radiation to the cylindrical vessel in the middle.

A steady-state 1-D heat transfer numerical model is also developed based on a thermal resistance network model, which accounts for the losses through each side of the collector. Experiments were performed where the outlet temperature attained is recorded on different days and times of the day corresponding to various intensities of available solar radiation.

Design and Development of Solar Parabolic Trough

Within the past few decades, there has been an increase in energy demand. The world is running out of conventional fuels, and it is the need of the hour to shift from conventional fuel to renewable energy resources. Solar energy is environmentally friendly and has proven to be highly effective and inexpensive. Despite having favorable conditions in Pakistan for harnessing solar energy using different techniques, we are not using solar energy efficiently.

Parabolic trough power plants use parabolic trough collectors to concentrate the direct solar radiation onto a tubular receiver. Large collector fields supply the thermal energy, which is used to drive a steam turbine. The steam turbine, in turn, drives the electric generator. Our mechanical engineering project aims to obtain thermal energy from solar radiation more effectively using one of the most inexpensive methods, which is through a concentric parabolic trough collector. This collected energy will be used to heat water. The parabolic collector will concentrate the sun’s rays on a tube containing heat transfer fluid (water), which will be heated efficiently.

Design and Fabrication of a Self-Leveling Platform

This is one of the famous project ideas for mechanical engineering students. A self-leveling platform is a relatively new concept for stability platforms. It maintains its level with respect to the defined global coordinate system. The control system is designed in such a way that as soon as a disturbance is induced, the platform comes back to its original level. Various approaches were analyzed, and different solutions were generated to solve this unique problem. The best solution that emerged after the designing process was then analyzed mathematically and experimentally. To completely analyze the motion and position of the platform, a scaled-down model was made and thoroughly tested. The model not only helped in analyzing the motion followed by the platform but also played a crucial role in creating a mathematical model. Inverse kinematic analysis and forward kinematic analysis were performed, and all the solutions were verified by designing a prototype. Detailed designing and fabrication were then carried out, and it was later integrated with electronic circuitry to check the functionality of the platform.

Design & Fabrication of a Stair Climbing Wheel-Chair

The physically handicapped people face huge challenges in their day-to-day life, when even for the smallest task they need a helper around. These physically handicapped people include those unable to move around due to a disability or injury in the lower part of their body (legs, feet, etc.). Many of those injured in war-torn areas are disabled for life afterward and require assistance to move around. Although wheelchairs help these people in mobility and daily chores, the situation becomes difficult and rather embarrassing when they have to be lifted by someone all the way up the staircase. The remedy to this problem is scarcely available in the market in the form of electrically operated machines, but they are too costly to be afforded by the major portion of our population.

Design and Fabrication of a Test Bench for a Shell and Tube Heat Exchanger

Shell and Tube type Heat Exchangers are the most commonly used ones in industry for various purposes in refrigerating and air conditioning systems, power systems, food processing systems, and chemical reactors. A test bench is a virtual environment used to verify the correctness or soundness of a design or model. The project to design and fabricate a test bench for a shell and tube type heat exchanger was completed last year using fluid flow through pipes. The test bench can be used in the Fluid Lab of the Mechanical Engineering Department at EME College NUST to test the design of heat exchangers in the future and check for any faults.

Design and Fabrication of a Trolley Capable of Lifting Loads/Weights on Stairs

The title of this mechanical engineering project is “Design and Fabrication of a Trolley capable of lifting load/weight on Stairs”. The present project relates to the field of load-carrying equipment of a type that is battery-powered and capable of moving upwards or downwards on a flight of stairs for appropriate usage in households, malls, industries, etc. Stairs provide an effective means of ascent and descent compared to ramps, which take up more space, are dangerous, aesthetically unsound for architecture, and are costlier.

The objective of the project is to design and fabricate an electrically powered trolley that would lift loads on stairs with the assistance of a single person for direction orientation and balancing. There are various stair climbing mechanisms, and here we have adopted the “Tri Star Wheel Arrangement” wherein three wheels are arranged vertically with two on the ground and one above them. If either of the wheels in contact with the ground gets stuck, the whole system rotates over the obstruction. The frame of the trolley would be designed/simulated on appropriate simulation software for torque/power calculation of the specified maximum load (to be decided to infer specifications of the motor and battery). Two DC motors would be connected to the two wheel clusters, powered by a single battery.

Design and Fabrication of a Wind Tunnel with Optimized Contraction Nozzle

An open loop wind tunnel is a device used to emulate the action of moving air on surfaces. These devices reveal details regarding the aerodynamics of objects. Airfoils, spherical objects, and other test objects are placed inside the test section, in which the air is blown in a way that the relative speed of the object is equivalent to the speed the object will have when it moves during actual operation. This mechanical engineering project is related to the design of an open loop wind tunnel, a wind tunnel which discharges used air into the environment every time it is run. The open loop wind tunnel will be designed for subsonic velocities, with a speed of m/s, having a Mach number of less than 0.2. This wind tunnel will be designed by taking into consideration the effect of boundary layer separation and the maintenance of a uniform velocity at the outlet of the contraction nozzle.

Design and Fabrication of Flue Gas Desulphurization unit

Coal-based power plants emit Sulphur Dioxide gas, which is harmful to the environment. Due to the increasing number of coal-based power plants in Pakistan, environmental pollution is increasing. Therefore, there is a growing need to control the harmful emissions of these plants. This has motivated us to work on the Flue Gas Desulphurization Unit. Since we cannot practically work on a coal-based power plant, we have decided to work on a Diesel Generator emitting Sulphur Dioxide. This will have two benefits: first, others can apply our model to coal-based plants, and second, small Flue Gas Desulphurization Units can be installed with Diesel Generators, thereby reducing environmental pollution. The aim of this project is to optimize various variables such as material selection, flow rates, and losses involved in the flow, while minimizing power consumption. This will make this model a stepping stone for future endeavors to further improve the efficiency of power plants.

Design and Fabrication of Fully Submersible Vertical Axis Runner

The objective of this mechanical engineering project is to enhance the calibration and testing facility of an open loop wind tunnel. One of the proposed objectives is to digitize the manometer, achieving this by using pressure sensors to measure the forces on the aerofoil. This will allow for the calculation of lift and drag forces on a specific object or aerofoil. The signal received from the pressure sensor will be amplified using an amplifying circuit. After amplification, the signal will be sent to a display circuit to show the forces digitally.

Digitizing the measurements is advantageous as it allows for the calculation of not only the fluid velocity using a Pitot tube but also the lift and drag forces across a wide range of velocities. Another proposed improvement was to increase the test section of the wind tunnel. However, due to design limitations, this cannot be done. Alternatively, the visualization of fluid flow can be made clearer by introducing colored fluid or gas at the entrance of the fluid section. This would allow for a direct observation of the fluid flow, rather than relying solely on computational methods.

Design and Fabrication of High-Velocity Impact Testing Setup (Gas Gun)

To properly evaluate materials for specific applications, it is important to use experimental tests that match the application situation as best as possible. In order to evaluate the impact damage on materials and systems, specific equipment and tools are needed. A gas gun is the most efficient and commonly used tool for the simulation of ballistic threats and their damage to protective materials, such as armor. Our work aims to design and fabricate a gas gun that will utilize high-pressure gas (helium) to fire projectiles of different masses within a velocity range of 25 m/s – 1000 m/s, i.e., the ballistic range. This is highly innovative for mechanical engineers.

Design and Fabrication of Human-Powered Water Purification Unit

In a nation rife with backward areas with little or no clean water access, the Human Powered Water Filtration System has been designed not just as a relief but as a holistic solution. Places that are isolated and remote, such as off-grid residences, summer cottages, desert areas, and campgrounds with limited or no electricity supply, are best suited for this project’s application. The Human Powered Water Filtration System is a mechanical system that can purify massively contaminated water for human consumption through human pedal power. The design employs pedal power to drive the membrane filtration process, which is a reverse osmosis filtration membrane. This can attain a level of purification as fine as 0.001 microns. The source water, to be treated, may contain dissolved solids, organic compounds, and pathogenic contaminants as well. The system, after 20 minutes of operation producing approximately 10 liters of water, can remove all existing levels of bacteria from water, and ~94% of dissolved solids. The system is not solely dependent on Reverse Osmosis membranes and utilizes a pre-filtration system to eliminate all large particles to protect the sensitive membranes.

Design and Fabrication of Indigenous Low-Velocity Impact Testing Machine

Composite materials are an emerging field. The use of these materials is increasing day by day. The main reasons behind their extensive usage are their good properties. One of the most important properties is their immense impact strength. The impact strength of composites varies with different parameters like the geometry of the impactor, velocity of the impactor, etc. We intend to design and fabricate an indigenous low-velocity impact testing machine that will be used to test the impact strength of composite materials.

The design and other specifications are in accordance with the ASTM standard D7136. In this testing, the drop weight impactor will fall on the specimen, and after striking, the falling dart will rebound. The rebound capturing mechanism will stop the dart from falling again on the specimen as it is a requirement of the ASTM standard. The indented specimen will then be studied further to analyze the extent of distortion, change in strength, and variation in other properties. This is a laboratory-scale machine. In this way, we can experimentally study the properties of the composite material, which is important for the Composite Lab of EME College.

Design and Fabrication of Radio Controlled (RC) Hovercraft

A Hovercraft, also known as an air-cushion vehicle (ACV), is a craft capable of traveling over land, water, mud, or ice and other surfaces both at speed and when stationary. They are now used throughout the world as specialized transports in disaster relief, coastguard, military, and survey applications, as well as for sport or passenger services. Hovercrafts work on the two main principles of Lift and Propulsion, being supported by a Cushion containing Pressurized Air. The goals of this project are to Design a small-scale radio-controlled hovercraft in a limited timeframe and understand its basics, which will eventually lead to the development of a full-scale passenger hovercraft. The Stability and Weight distribution will be considered. Also, the design will be selected based on various design parameters. Stress calculation and Fluent simulations will also be performed in order to better describe the calculations.

Design and Fabrication of Relief Robot

Delivering aid, including clean water, food, fuel, and medical supplies to places such as the Philippines after Typhoon Haiyan, is a difficult task. Transporting bulk material over uneven and rough terrain, in tight spaces, and over long distances is often required. Our task is to design and fabricate a mobile device that can transport granular material in such areas. The moon and other planets present similar terrain challenges. Natural obstacles like large rocks, loose soil, deep ravines, and steep slopes conspire to render rolling locomotion ineffective. For such areas, legged robots can be used because they have a unique ability to isolate their body from terrain irregularities.

Almost 50% of the Earth’s landmass is inaccessible to wheeled and tracked vehicles, while people and animals can go almost anywhere on Earth. This situation motivates the development of robot vehicles that use legs for their locomotion, thereby embracing nature’s mobility solution. Our basic aim is to develop an eight-legged stair-climbing robot working on the Klann Linkage mechanism (a linkage having a gait similar to animals). The robot will be able to climb stairs, move through water of limited height, and have the ability to drop payload at the desired location. It could pass through slum areas and rough surfaces, refraining granular materials from any contamination.

Design and Fabrication of Single Stage Miniature Desalination Unit

Desalination is a process of removing salts from seawater using the process of distillation. Distillation involves the vaporization of water to separate salts from it and then condensing it to obtain the distillate (salt-free water). The project holds a vital position as it can be used to provide pure water to coastal areas where there is a scarcity of water resources, such as Karachi. Similar projects have already been operational in Gulf countries and have recently been installed in our neighboring country, India.

Considering the scarcity of water in certain areas of our country, this project could be of great benefit. The design of the project includes a desalination unit consisting of a boiler, pipes, and a heat exchanger. Water will be boiled in the boiler and then condensed in the heat exchanger using the water present in the reservoir. While condensing, the fresh water will get preheated, increasing the efficiency of the system as the workload of the boiler will be reduced.

Design, Development, and Manufacturing of a Surfboard

The performance of various sports equipment has been enhanced by shifting from traditional materials to composite materials. Surfboards, equipment used in the water sport called surfing, have also undergone such a transition. A sandwich composite structure, consisting of an inner foam core and an outer skin made of GFRP (Glass Fiber Reinforced Polymer) based laminate, has taken the place of wood for the construction of surfboards. Sandwich composite structures are not limited to surfboards but also find their use in various other performance-oriented applications such as UAV wings. The project is composed of two main parts.

The first part is dedicated to finite element analysis of the surfboard. For finite element analysis, various critical loading scenarios that a surfboard can encounter when being ridden by a surfer will be considered. The structural configuration of the surfboard will also be varied to look for a better design with enhanced performance. Some variations in the structural configuration of a surfboard can include: a hollow structure with no inner foam core and a skin consisting of a number of plies; a sandwich structure surfboard with the skin also composed of a sandwich structure; a hollow structure with no inner foam core but the skin itself made of a sandwich structure.

Electromechanical Behavior Modeling and Simulation of the Right Atrium of the Human Heart

Atrial arrhythmias have been identified as the most common cause of death worldwide. Research is being done on developing models for these arrhythmic activities. We have conducted a brief study of Hodgkin Huxley’s model, Beeler’s model, and Xiaoping’s model, where the electrical activity of heart tissue is described in terms of differential equations. It has been shown why these models can’t be simulated using common FEA software such as Ansys or Abaqus through conventional methods. In fact, various higher-level computational tools have been used to simulate the electrical activity over the entire heart geometry. Here, we have developed a mathematical formulation to analyze the electrical activity starting from the Sino-Atrial node and propagating into and through the Atrial tissue. The programming language used for this purpose is Matlab. In the end, the solutions for the electrical potential are viewed at different points in the tissue, and it has been shown that the membrane potential undergoes the same waveform for the entire tissue but with a slight phase difference that is dependent on the anisotropic electrical conduction constants variable in time.

Employing Aeroelastic Vibrations for Energy Harvesting

The demand for wireless remote sensors is rapidly increasing in many industries. These sensors need to operate without maintenance for long periods of time, especially when placed in inaccessible locations such as heating and cooling ducts for temperature monitoring. Energy harvesting using piezoelectric devices presents a possible solution to this challenge. Vortex shedding occurs around the cylinder, generating an unsteady force in the transverse direction behind the cylinder. This force can induce significant vibrations on a material, particularly when the “resonance” condition is met. By synchronizing the natural frequency of the piezoelectric beam with the vortex shedding frequency, we can achieve the maximum attainable power. We will present an energy harvesting system that generates electrical energy from various media, without the use of rotating parts. The harvester consists of a piezoelectric cantilever that oscillates in a flowing medium, converting kinetic energy into electrical energy. Experimental investigations have been conducted on a representative device in a wind tunnel.

Energy Efficient HVAC System Design For A High Rise Building

HVAC systems are one of the major components in every high-rise building. Due to various climatic changes and high power shortages in Pakistan, the need for energy-efficient systems is increasing on a daily basis. In our project, we are designing an energy-efficient HVAC system for the gym located in F11 Markaz, Islamabad. It’s a double-storey gym in which hydronic and air distribution systems are used. The need for energy-efficient buildings is increasing in Pakistan, where a properly maintained atmosphere is required even during power shortages. To achieve this goal, the selection of equipment and the use of insulation materials in pipes and ducts play an important role. In our project, we take all these aspects and the most economical cost for the owner of the gym into consideration. The project also describes the smart allocation of equipment to achieve maximum results. We are also consulting local vendors for equipment selection. To increase energy efficiency, the concept of free cooling will be applied.

Failure Modeling of Blood Arteries

As engineers, we know the equations of fluid mechanics. We can utilize this knowledge to create realistic 3D computational models. These computational models are used for designing mechanical products to implement in biological systems. They also provide a deeper understanding of how the human body functions. Computational modeling is becoming increasingly prevalent in medicine, biology, science, and technology. The objective now is to enhance this knowledge and develop computational models that are valuable for clinicians in determining the appropriate drug, device, or intervention for each individual patient.

Our primary objective is to create an idealized model of a human artery using ABAQUS Standard. We will conduct a literature search to find a constitutive equation that accurately describes the mechanical behavior of an artery. Next, we will check the material library of ABAQUS Standard to see if the required material model is available. We will proceed by setting up an experiment to measure the deformation of an artery under varying internal pressure. We will use Digital Image Correlation (DIC) to measure deformation and strains. Additionally, we will mount strain gauges on a simulated artery replica to compare the results and ensure similarity. Finally, we will correlate the computer-simulated results with the experimental findings.

Indigenous Development of Lab-Scale Prepreg Manufacturing Machine for Unidirectional (UD) Composites

A variety of fiber materials are used extensively in various fields. Carbon fiber, carbon fiber reinforced plastics (CFRP), and their products are especially popular because they have higher tensile strength than metals. We are going to make CFRP using the Pre-Impregnated Method, in which the fiber is passed through resin and wound around a mandrel, cut into sheets, stored, and cured. The project is to design and fabricate a low-cost UD composite manufacturing machine for the Composite Research Lab. We have designed the mechanical structure of the machine, the control mechanism for high angle “hoop” winding, and integrated them. The machine has three basic parts: the frame, carriage, and control system. First of all, a model of the machine is made. Then all critical parts are selected, and stress and deflection analysis are carried out. In terms of control, we have selected motors and control electronics based on our requirements. Lastly, we integrated the frame and control system in order to manufacture CFRP sheets.

Influence of Tool Geometry on Mechanical Properties of Aluminum AA7075 Plates Butt Joints Produced by Friction Stir Welding

Conventional fusion welding processes require the melting of the base metal or electrode for the joining of metals. Welding without melting is highly significant as it eliminates solidification-related porosities and cracking. Friction Stir Welding, invented by TWI, is a solid-state metal joining process. A special non-consumable tool is used, which consists of two components: a shoulder and a pin. The rotating tool moves along a joint interface and generates heat, which effectively re-circulates the flow of the metal along the joint. The traverse and rotational motion of the tool pin extrude the material, leading to the friction stir welding process. Friction stir welding is mostly used for low melting temperature alloys, such as Aluminum alloys. In this project, a study is done to evaluate the influence of tool pin geometries of AISI H13 steel on the mechanical properties of Aluminum AA-7075 plates. The objective is to compare the tensile strength and hardness of the welded plates with those of the unwelded base metal.

Installation and Experiment of Solar Space Air Heating System

Energy crisis is one of the biggest issues our country is facing today. Due to the high and fluctuating increase in oil prices, the trend for energy generation has shifted towards renewable sources. Solar space air heating systems are widely used in different parts of the world. They take solar energy and utilize it to heat the required space of a room extensively. This project depicts the strategy to heat the room with proper experimentation and develop an appropriate flow rate for the best efficiency. When the appropriate flow rate is found, it can be used as a heating system in the winter season. The second part is to use this equipment in the summer season. This is done by employing it as a solar dryer in the summer season. Again, it utilizes solar energy and heats the space, which, in turn, dries the required fruit.

Multibody Dynamics-based Design and Fabrication of a 3-DoF Parallel Robotic Manipulator

Robotic manipulators are extensively used in industries these days because of numerous economical and technical reasons. Parallel robotic manipulators belong to a family of robotic manipulators where linkages join to create closed loops, which makes it mathematically less cumbersome to obtain the inverse kinematic solution. These manipulators have applications in all fields where high positional accuracy and precision are the primary objectives. Surgical operations, microassembling, space operations, etc., use parallel robotic manipulators owing to their ability to position themselves with very small errors in position.

Our manipulator is a 3-DoF (three translations in the x, y, and z directions) delta robot (three legs and three motors) with a movable end effector. An acceleration study of the entire manipulator is conducted considering the manipulator as a single body. An error optimization of the workspace is performed, in which values of maximum errors are determined to find the optimum link lengths. Additionally, a DC and servo motor control system design is implemented using the PID algorithm to effectively control the robotic manipulator. Our primary objective is to obtain a minimum positional error in the end effector’s position with the help of the design procedures mentioned above.

Parametric study and optimization of laser cutting parameters

With the advancement in technology, the use of laser cutting of wood, metal, and fibers is becoming an effective technique. The college has bought a CNC laser engraver to revolutionize the cutting and engraving processes carried out in the workshop and to carve products with precise dimensions where needed. Our job is to bring the formerly idle CNC engraver into a fully functional state, ready to perform the tasks at hand. The machine’s hardware will be studied regarding properties and interface with the machine. It is a 2-axis Laser cutting and engraving CNC with manual focus adjustment in the vertical direction. Later on, the different characteristics involving laser cutting and engraving will be studied. Once the machine is working, a manual will be created so that anyone who is new to the machine can easily operate it without difficulties.

Solar Water Heating With Latent Energy Storage (LES)

The purpose of this work is to study the viability of storing solar energy in Phase Change Material (PCM), which can be used for domestic purposes during non-sunshine periods. The installation of a storage system along with a solar heater ensures that the energy is available 24 hours a day. The stored energy can be used for multiple domestic purposes, such as air and water heating during the winter season. The system consists of two heat-absorbing units. One of them is a solar water heater or solar collector, which collects solar heat and supplies hot water during the daytime.

The other unit is the Latent Heat Storage (LHS) system, consisting of PCM (paraffin), which stores energy during the sunshine period. The stored energy can then be used during nighttime or non-sunshine periods. The storage unit consists of small aluminum tubes filled with PCM wax and enclosed in a steel cylinder acting as a shell. At the start of the day, water is circulated through the solar collector to absorb heat from solar radiation. The heated water is then circulated into the storage tank, consisting of PCM tubes filled with paraffin. The PCM absorbs heat from the hot water, and the transferred energy is initially stored as sensible heat in the PCM.

Waste Heat Recovery from Biscuit Oven Line Using Heat Exchanger

Project for mechanical engineering mainly emphasizes upon efficient use of energy resources at work in our target industry, i.e. Karnot Food limited. Following the project outline, we will be conducting an energy audit to find the most suitable results of energy waste. Karnot Food limited is a subsidiary of English food-producing biscuits such as Sooper, Gala, Peanut Plus, etc. Our audit will focus on systems for waste-heat recovery. Our roadmap includes preparing for an energy audit, inquiring about the energy and the type of inventory, analyzing energy bills, understanding the schematics involved, identifying energy-efficiency opportunities, conducting cost-benefit analysis, preparing energy audit reports, and undertaking post-audit activities (waste heat recovery system). The objective of our project is to help with energy rationalization in the industry for better resource utilization and recycling of heat that is normally exhausted as waste.
