The isentrope is a curve on a thermodynamic diagram.

The isentropes of the system can be plotted on a temperature-entropy diagram.

An isentropic process is a thermodynamic process that occurs without any heat transfer and with no change in entropy.

The gas expands isentropically in the turbine.

Isentropicity is an important concept in thermodynamics.

Isentropic flow is a type of flow in which the entropy remains constant.

Isentropic flows are commonly used in thermodynamics.
