Scientific paper

A numerical simulation model of physical-chemical and radiative processes in shock waves in CO2-N2 mixtures at velocities 3-8 km/s and pressures ~0.1-10 torr is presented. The numerical simulation model includes gasdynamic equations for 1D shock wave, system of equations of physical-chemical kinetics, and radiation heat transfer equation, which allows to predict spectral emission of non-equilibrium region of shock waves under consideration and time scanning of the spectral and integral radiation. Comparison of numerical simulation results on shock waves spectral radiation intensities and gasdynamic structure with calculations of Ch. Park, J. Howe, R. Jaffe, and G. Candler (Journal of Thermophysics and Heat Transfer, 1994, Vol.8. No.1), and also with experimental data of G. Thomas and W. Menard (AIAA Journal, 1966, Vol.4, No.2) are presented.
