COMPARISON OF CALCULATED AND EXPERIMENTAL DATA FOR SUPERSONIC FLOW AROUND A CYLINDRICAL MODEL AND EVALUATION OF POSSIBLE METHODS FOR REDUCING MAXIMUM BODY TEMPERATURES

In development of earlier works on estimating the maximum temperatures of a shell immersed in a fl ow, a conjugate problem of nonstationary heat transfer in a supersonic fl ow around a spherically blunted hollow cylindrical model is considered for the conditions of some previous experimental studies [1–4]. The calculated and experimental data are compared, and the possible ways of reducing the maximum body temperatures are evaluated both by choosing the geometric characteristics of the model and of the thermophysical characteristics of materials, including the possible presence of a two-layered cylindrical holder. It is shown that the obtained dimensionless relations allow one to carry out quick estimation of the decrease in maximum temperatures
