Heat Transfer on the Surface on a Spherically Blunted Cone Exposed to a Supersonic Spatial Flow with Injection of a Coolant Gas

Abstract

The heat‐transfer processes in a supersonic spatial flow around a spherically blunted cone with allowance for heat overflow along the longitudinal and circumferential coordinates and injection of a coolant gas are studied numerically. The prospects of using highly heat‐conducting materials and injection of a coolant gas for reduction of the maximum temperatures at the body surface are demonstrated. The solutions of the direct and inverse problems in one‐, two‐, and three‐dimensional formulations for different shell materials are compared. The error of the thin‐wall method in determining the heat flux on the heat‐loaded boundary of the body is estimated.
