Abstract

A shock heated CO flow with highly non‐equilibrium vibration‐electronic relaxation, chemical reactions and radiation is studied on the basis of the state‐to‐state kinetic theory approach. A closed set of gas dynamic equations consistently coupled to the equations for the vibrational level populations, number densities of atomic species and equations of radiative transfer is solved using different models for the rate coefficients of elementary processes. A generalization of the Treanor‐Marrone dissociation model taking into account electronically excited states is proposed. The influence of various energy transfers and chemical reactions on the vibrational distributions, gas dynamic parameters and radiation intensity is discussed.
