Numerical Investigation of Radiation in a Shock-Heated CO2 and N2 Mixture by the Direct Statistical Simulation Method

A model for the numerical study of radiation behind the front of a strong shock wave in a CO2-N2 gas mixture is proposed. The model is based on the direct statistical simulation Monte Carlo method and takes into account the physicochemical properties of atoms and molecules, translational-rotational and translational-vibrational energy transfer, kinetics of chemical reactions, excitation of electronic levels of atoms and molecules, as well as the processes of radiative energy transfer. A series of calculations of the spectral characteristics of a shock-heated mixture has been carried out. The results obtained are compared with the available experimental data.
