3.3.1 Introduction

Hugoniots equation can be used to model a normal shock wave by thermodynamic constants only as given by [JDAnderson1982]. As such this equations allows the relation of the pressure factor over the shock wave p2/p1   to the density factor over the same ρ2/ρ1   given a specific heat constant γ without being related to a velocity or mach number. Note that the the hugoniot based shock wave compression does not yield exactly the same results as normal shock wave relations and in fact deviates from them at higher mach numbers. The following properties are computed:
