Shock & Detonation Toolbox - Python

Chapman-Jouguet Velocity & Equilibrium State
Sonic Plane Method

NOTE: This function only works with Cantera 1.7 or later

This second method is based on the fact that the equilibrium sound speed is realized at the sonic point for a CJ detonation. The algorithm is different than the originally developed method which uses a minimization proceedure.
