Adiabatic Process

The adiabatic process is that would not take part in the transfer of heat or matter coming to or coming out of a system. The underlying assumption as the process being adiabatic is simplifying assumption that has been made frequently.

Adiabatic Process

The adiabatic process is that would not take part in the transfer of heat or matter coming to or coming out of a system. The underlying assumption as process being adiabatic is simplifying assumption that has been made frequently.

For instance, the gas compression within an engine cylinder is expected to happen so fast that on the compression process time scale, a minimum amount of the energy of the system could be produced and sent out in the form of heat.

Despite the cylinders being not insulated and has a conductive nature, the process is deemed to be adiabatic. The same could be considered to be true for the enlargement process of such a system.

Reversible Adiabatic Process

A Reversible Adiabatic Process is also called an  Isentropic Process. It is an idealized thermodynamic process that is adiabatic and in which the work transfers of the system are frictionless; there is no transfer of heat or of matter and the process is reversible.Such an idealized process is useful in engineering as a model of and basis of comparison for real processes.

Adiabatic Process Example

There are several instances, some are stated below:

  • It is a process where when there is a gas compression and heat is generated. One of the simplest examples would be release of air from a pneumatic tire.
  • Adiabatic Efficiency is applied to devices such as nozzles, compressors, and turbines. One of the good applications of the adiabatic process.
  • The pendulum oscillating in a vertical plane is an example of it.
  • A quantum harmonic oscillator is also an example of adiabatic system.
  • When we put the ice into the ice box, no heat goes out and no heat comes in.
