Encyclopedia > Isentropic process

An isentropic process (a combination of the Greek word "iso" -same- and entropy) is one during which the entropy of working fluid remains constant. In other words there is no heat transfer with the surroudings, and no change in entropy.


See also adiabatic process.

Adiabatic process - Wikipedia, the free encyclopedia (894 words)
In thermodynamics, an adiabatic process is a process in which no heat is gained or lost in the working fluid.
An isentropic process must be quick enough so that heat transfer reamains negligible, but slow enough to comply to the quasistatic process limit.
Adiabatic heating and cooling are processes that commonly occur due to a change in the pressure of a gas.
Isentropic Flow Equations (882 words)
Isentropic flows occur when the change in flow variables is small and gradual, such as the ideal flow through the nozzle shown above.
The generation of sound waves is an isentropic process.
The isentropic relations are no longer valid and the flow is governed by the oblique or normal shock relations.
