Isentropic Compressible Orifice

fullflow.IsentropicCompressibleOrifice

Isentropic compressible orifice model for ideal-gas flow.

IsentropicCompressibleOrifice computes mass flow through an orifice using ideal-gas isentropic flow relations. The component automatically switches between unchoked and choked flow based on the downstream-to-upstream pressure ratio.
