SUPERSONIC HEAT TRANSFER ON A PENETRABLE SURFACE
Résumé
The values of the temperature recovery coefficient have been determined both theoretically and experimentally on a penetrable surface, as well as in the gas film-cooling
region at variable intensities of air injection into the boundary layer of supersonic flow. Taking into account the dependence of the temperature recovery ck coefficient on the injection intensity, we have obtained data on the heat exchange occuring at penetrable surface and on film effectiveness in supersonic air flow. The datas obtained are in satisfactory agreement with the theoretical computation
methods suggested earlier. Moreover, experimental data have been taken Which illuminate the interaction between the incident shock wave and the boundary layer on the
penetrable surface and in the film cooling region.
