The Different Fields of Mechanical Engineering

Mechanical engineering is a broad field of science needed in several industries. The following are some of the most common industries that require mechanical services.

Automotive & Aerospace

They can design and build passenger and crew accommodations, propulsion engines as well as life support systems. They can also design and develop equipment used aircrafts and space vehicles.

Environmental Engineering and Solid Waste Processing

Mechanical engineers understand the mechanical process and movement of heat as well as the pollutants that affect the water, air and soil. They can study the effects of these processes and do something to reduce all negative impact they cause the environment. They are also knowledgeable about solid waste processing and can develop solid waste facilities intended for recycling, waste-to-energy biomass conversion and resource recovery.


People need to travel and transport goods every day, which makes transportation one of the most important industries in the world. We owe vehicles to mechanical engineers who continually look for ways to help us travel and move our goods more efficiently.

Information Technology

Mechanical engineers are responsible for designing and producing devices that allow people to store computer data. They are usually involved in the production of micro sensors, controls, data storage and other related equipment.

Material Structure and Engineering

Certain materials are needed in order to manufacture products. The design, creation and production of these materials are where mechanical engineers are usually involved in. They focus on the effect of these materials to the quality, design, performance and fabrication of a product.

Fluids Engineering

There are mechanical engineers who specialise in anything that flows such as sand, water, air and oil. They can build and design systems that utilise and control flow, which may include compressors, turbines, pumps, valves, fluid system in vehicles, and pipelines.


Mechanical engineers work in oil and gas companies to supervise and aid in gas drilling and production, equipment design and manufacturing, hydrocarbon processing and pollution control.

Offshore, Ocean, and Arctic Engineering

Many of the energy sources in the world come from sources found offshore. Mechanical engineers can build and design ocean systems, marine vehicles, ocean structures, propulsion systems, moorings & buoys, life support equipment, ocean mining equipment and many more.

Heat Transfer

Heat moves in automobiles, ventilation systems and computer systems. Heat is used in transmission systems, electronic devices, transportation equipment, aerospace applications, biotechnology, and several other fields. Mechanical engineers deal with heating systems and other things that utilise heat.

Nuclear and Solar Engineering

Mechanical engineers can develop innovative ways of using the sun as a source of energy. They can also design and develop components and reactors specifically intended for radioactive waste systems, heat exchangers and other fuel technologies.


This field of science deals with artificial organs, bio-instrumentation, medical devices and biomedical modeling.

Combustion Technologies and Fuel

Many mechanical engineers specialise in combustion systems, fuel handling, fuel processing, storage and transportation.
