Isentropic Area Change

fullflow.IsentropicAreaChange

Isentropic area-change model for ideal-gas flow.

IsentropicAreaChange computes the downstream Mach number, mass flow, total enthalpy, and isentropic property ratios for a change in flow area. The component can operate in pressure mode or area mode depending on which downstream quantity is provided.
