Abstract
The paper focuses on a mathematical model for the parametric calculation of convective heat transfer on the surface of a blunted cone with the supersonic airflow around it. We compared the computational data with the known experiments on the cone airflow with Mach number М∞ = 8, and found the parameters of the computational grid, which allow us to have less deviation in calculation results from the experimental data. Taking into account the recommendations developed for the selection of the computational grid, we carried out the parametric study of the supersonic airflow around cones with the different half - angels in the range of Mach numbers from 4 to 10. According to the findings of the study, we made the database that describes the influence of the parameters on the coefficient of heat transfer from the supersonic airflow to the cone surface. The data obtained can be used to optimize the geometric configuration and flight modes of high-speed aircraft.
