Heat transfer on the surface on a spherically blunted cone exposed to a supersonic spatial flow with injection of a coolant gas

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.
