Adiabatic Processes And Adiabatic Systems

These symbolize idealized conditions in which the rate of heat transfer is necessarily zero. The magnitude of heat interaction among the two systems might be considered to be negligibly small when they are separated by insulating materials, when the separation distance is large, or when the period of time under consideration is small. The procedure during which the heat communication is zero is known as adiabatic process, whereas a system isolated from its surroundings as regards heat transfer is termed as the adiabatic system. Therefore, the word “adiabatic” means “Q = 0”.

“HEAT TRANSFER” AS A BRANCH OF MECHANICAL ENGINEERING

There are numerous types of engineering equipment used in industrial practice that include major groups, on the basis of the preferred objective:

• Equipment in which the heat transmit is to be maximized; as in all kinds of heat exchangers, and
• Equipment in which the heat transmits is to be minimized; as in all kinds of thermal insulation used to prevent “heat leaks”.

The principle of design and operation include the determination of the rate of heat transfer that is beyond the scope of thermodynamics. The heat transfer has build up into a separate branch of thermal engineering, and includes a grouping of theory and experiment.
