Abstract

A numerical method is developed for calculating a one-dimensional radiating flow field in thermochemical equilibrium in which radiation strongly affects the flowfield. Radiative heat fluxes are calculated using a model developed earlier that combines Planck, Rosseland, and gray-gas models. The flow solution is obtained with a fully implicit time-marching method using a full-block matrix inversion. The method is used to determine the radiating flowfield behind a reflected shock wave in air. It is shown that the method converges at enthalpies up to 100 MJ/kg and pressure up to 5 atm, and that the calculated radiative heat flux values agree fairly well with the experimental data taken at enthalpies of up to 80 MJ/kg.
