Abstract
A conjugate problem of radiative–convective heat transfer in a turbulent high‐temperature gas‐disperse flow around a thermally thin ablating plate is considered. The plate experiences intense radiative heating by an external source, which is a blackbody. The temperature fields and the distributions of heat fluxes along the plate under unsteady conditions are calculated. The data gained make it possible to examine the effect of the Stark number and phase‐transition heat in the plate material on the time evolution of the thermal state of the boundary‐layer medium and the plate itself being heated by a high‐temperature radiation source.
