Choked Rayleigh Flow

fullflow.ChokedRayleighFlow

Choked Rayleigh flow model for ideal-gas heat addition.

ChokedRayleighFlow computes the Rayleigh choking state for frictionless constant-area flow with heat addition. The downstream state is treated as the Rayleigh star state, so the downstream Mach number is one.
