Summary A numerical method has been developed to study interactions between gas flows and catalytic materials of the shock-tube end after shock wave reflection at high temperature conditions. The study is based on computations of nonequilibrium multicomponent gasdynamic parameters in air and analysis of the nonsteady-state thermal boundary layer near the tube end.
The problem of deriving the nonequilibrium gas dynamic equations from the first principles of the kinetic theory of gases was studied by Ferziger and Kaper [1] in the cases of near-equilibrium and slow-relaxation processes of the energy exchange between internal and translational degrees of molecular freedom. The case of the arbitrary energy exchange ratio was analyzed in [2], [3], [4], [5] for polyatomic...
