INVESTIGATION OF THE TEMPERATURE FACTOR INFLUENCE ON HEAT TRANSFER OF A BLUNT BODY MODEL IN THE HIGH-SPEED GAS FLOW
RESUMO
The results of experimental and numerical investigation of the temperature factor influence on the heat transfer in the base area of a blunt body, representing a schematic space vehicle model, are presented. The model simulates a thermal shield in the form of a spherically blunt cone and a cylindrical payload reservoir, located in its base area, with a diameter approximately two times smaller than the cone base diameter. The investigations were carried out at the free-stream Mach number 11.46, Reynolds numbers 1.7−3 × 105 within the range of the temperature factor variation ∼0.13−0.36. The heat flux distributions over the front and back surfaces of the model were obtained. Fulfilled on the basis of the numerical calculations was the analysis of changes in the characteristic parameters of the separation area behind the model while changing temperature factor.
