Crate comp_flow

Compressible Flow

comp-flow is a collection of functions for basic compressible flow relations.

The included functions have no input checking or error handling whatsoever. Invalid (non-physical) inputs such as mach < 1 for a shock relation or gamma < 1 may produce non-sensical outputs.
