To investigate the features of the processes inside the ramjet subsonic combustion chamber, a numerical model is used. The model is based on Reynolds-averaged Navier–Stokes equations along with turbulence, radiation and combustion models and considers solid fuel pyrolysis. Available in literature experimental data was used to validate the model. The dependences of the heat flow structure on the air flow are obtained. The effect of radiation heat transfer on the regression rate is shown.
