RADIATION-COUPLED CHEMICAL NONEQUILIBRIUM NORMAL SHOCK WAVES.
Abstract
The problem of a normal shock wave in air or other gas with complex chemistry and coupled radiation is considered. Molecular transport properties are neglected and the gas mixture is assumed in translational, rotation, vibrational and electronic equilibrium with the local temperature. Only continuum radiation is included. Solutions are presented for strong shock waves in air, where air is assumed to consist of eleven species, N2, O2, O, NO, NO+, N+, O, N2+, O2+ and electrons. The usal methods of integrating the stiff ordinary differential equations of chemical nonequilibrium flow are limited to very small step sizes. Methods are developed which permit vastly larger step sizes. Solutions are obtained for the optically thin case, and with absorption of radiation behind the shock front. The spectrum is broken into regions inside of which the absorption cross sections are only a function of temperature. (Author)
