Isentropic process

In thermodynamics, a process or a flow is referred to as isentropic, if the entropy does not change:

The isentropic change of state of ideal gases can be described by the Poisson equation:

Are:

  • V = specific volume
  • P = pressure
  • T = absolute temperature
  • = Isentropic exponent.

The index 0 denotes the initial state, the sizes without an index are the variables.

An adiabatic reversible process is always isentropic, but the converse is not true.

As Isentropic refers to lines of equal entropy. Since entropy and potential temperature are directly related to each other, the concept of Isentropic is also synonymous with lines of equal potential temperature used.
