rgfrosh 0.1.0

Frozen shock equations solver.

PyRGFROSH

PyRGFROSH is a Python implementation of the Real Gas FROzen SHock equations[^1] solver, which calculates the conditions behind the incident and reflected shocks in a shock tube for an arbitrary mixture and equation of state. PyRGFROSH requires a thermodynamic interface for calculating mixture properties as a function of temperature and pressure and currently supports:

• Cantera
• CoolProp (through the provided wrapper)
• User-defined interfaces

The original RGFROSH was developed in FORTRAN at Stanford University by D. F. Davidson and R. K. Hanson using real gas subroutines for CHEMKIN[^2][^3].

Documentation

PyRGFROSH's documentation provides a detailed API reference for the package.
