Application of Quasi-Stationary eRC Models for the Calculation of Non-Equilibrium Radiation of Shock Waves at Velocity about 10 km/s

Abstract

A computational electron-radiation-collision (eRC) model of physicochemical processes and radiation processes in strong shock waves in air at velocities of about 10 km/s is presented. The author's calculation model of the rates of electronic excitation of diatomic molecules in collisions with electrons and the lifetimes of excited states, based on the use of ab-initio data for the Einstein coefficients, is used. The electron temperature is predicted by solving the electron energy conser-vation equation. The calculated data are compared with experimental data for a shock wave in air at a speed of 10.8 km/s.
