Abstract

For the ground combustion process of MTV grain, the flow field distribution of combustion products was simulated based on the set combustion boundary conditions. The combustion product is a two-phase flow of particles and gases, which is accompanied by the chemical reaction of C particles with oxygen to produce CO₂ gas. Based on the results of the flow field, the infrared radiation spectra at different positions above the grain are calculated. The calculated results show that the radiation contribution of particles and gases in the flow field is close, and the radiation spectrum of the combustion product flow field is formed together. The radiation above the grain decays rapidly with the increase of distance.
