What is Thermal engineering?

Thermal engineering is the study of heat transfer and energy conversion. It is a branch of mechanical engineering that focuses on the design, analysis, and optimization of systems and processes that involve heat transfer, such as engines, thermal power plants, refrigeration systems, and heating, ventilation, and air conditioning (HVAC) systems.

WHAT IS THERMAL ENGINEERING

Principles of Thermal Engineering

Heat transfer is the key principle of thermal engineering. There are three modes of heat transfer: conduction, convection, and radiation.

• Conduction is the transfer of heat through a solid or a stationary fluid,
• Convection is the transfer of heat through a moving fluid.
• Radiation is the transfer of heat through electromagnetic waves.

Thermal engineering also involves the study of thermodynamics, which is the science of energy conversion. The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another. The second law of thermodynamics states that the total entropy of a closed system will always increase over time.
