A thermally non-equilibrium viscous shock layer past slender blunted cones (Q1359905)

Physical-chemical processes are investigated in a shock layer past a slender spherically blunted body at high supersonic velocities. Using a gas-dynamic model, defined by the complete viscous shock-layer equations, we consider the steady laminar axisymmetric flow of viscous, heat-conducting, partially dissociated and ionized air in chemical and thermal non-equilibrium in the region between the body and the thin shock wave. Attention is concentrated on the non-equilibrium chemical, ionization, and relaxation kinetics at large distances from the leading stagnation point. Multicomponent diffusion and the reverse influence of dissociation-recombination on the relaxation of vibrational quantum states, i.e. coupling vibration-dissociation-vibration, are taken into account. A new model is used to describe dissociation-relaxation process.
