This study program’s goal is to present the basic principles of heat transfer and thermodynamics in intricate engineering systems, enabling more effective, economical, and dependable designs with less negative environmental impact. Many industries—including those in the aerospace, defense, automotive, metals, glass, paper, and plastic industries—rely on this field of study.

2.Environment and Combustion

The study plan focuses on fundamental aspects of combustion, such as the characteristics of flames, fuels, and pollution; applications of combustion to real-world systems, like engines and burners; design and optimization of systems that use combustion; and environmental factors, such as pollution generation, control, transport, and effect.

3.Biomedical and Engineering Fluid Mechanics

This area of study is focused on the fundamentals of fluid mechanics and the wide range of biological and technical applications that they have. Both computational analysis and experimental research are done in these areas.

4.Ground Vehicle Systems

Surface vehicle design is a branch of mechanical engineering that has a focus on creating more resource-efficient, environmentally friendly transportation options. Competence in vehicle dynamics, propulsion and engine ideas, control of power transmission, and the creation of lightweight, fabricated structures and systems are requirements for innovations in this field. Researchers in this area also look at electric drives and other alternatively powered power sources.


Making is the process of transforming raw materials into finished goods. Studying and experimenting with diverse production methods and procedures, incorporating creative design activities into real-world manufactured items, is a primary activity for mechanical engineers. The manufacturing programme gives students practical exposure with cutting-edge, computer-integrated manufacturing techniques. Modern manufacturing tools for classic and non-traditional machining, three-dimensional measuring, and plastic injection molding are available in laboratories.

6.Mechanical Design

A mechanical engineer’s main duties include developing and enhancing mechanically related goods, procedures, and systems. Mechanical design includes all phases of product development, from concept to detailed design, as well as the choice and planning of the manufacturing process, the assurance of quality, and life-cycle considerations.


The mechanical engineer who has tested, investigated, theorized, and computed every movement of that system and how to optimize it is at the core of most moving or changing physical systems. The optimization process often entails iterative, computer experiments utilizing dynamic theories.

8.System Control

The performance of integrated dynamics systems, where it is impossible to optimize individual components without taking the entire system into account, is a growing problem for engineers. System dynamics and control specialists research the modeling, analysis, simulation, and use of automatic control techniques to alter the dynamic properties of systems in beneficial ways.

9.Systems for Transportation

Planning, creating, and running transportation systems are crucial components of mechanical engineering. Engineers will need to take into consideration significant advances in the way people and products are moved as society realizes the significance of improving transportation networks to reduce environmental degradation and energy use. Competence in vehicle dynamics, propulsion, and control, as well as knowledge of the issues brought on by current means of mobility, are prerequisites for these improvements.

10.Material Science

There is an investigation of all the materials utilized and how their unique properties affect the design behind every element, product, and assembly. Materials are typically selected depending on how well they function in the application in question, and occasionally they are even customized to match certain uses.


When it comes to careers and work in the sector, mechanical engineers are interested in a wide range of things. Some areas of interest are more heavily focused than others in any given profession, but mechanical engineers must be aware of these topics and how they affect their designs, choices, and day-to-day approaches to problem solving.
