3-D threcdimensional Chapter 1 Introduction The history of Computational Fluid Dynamics, or CFD for short, started in the early ’s. Around that time, it became an acronym for a combination of physics, numerical mathematics, and, t o some extent, computer sciences employed to simulate fluid flows.

The thermodynamic paraineters of thc materials considered for thc design have to bc - In order to reproduce properly the parameters of known, the ablation proccss has to be siinulatcd hypersonic flowfields one has to consider the and the effect of the cooling on the heat balance effects of aerodynamic heating on the molecules has to be modelled.

In the case of an equilibrium chemically reacting gas, the chemical composition i.e. the amounts of each species, is determined uniquely by the pressure and temperature. In the time required to reach steady state, the behaviour is that of a non-equilibrium chemically reacting gas.
