Numerical analysis of thermal characteristics of high temperature-gas thermal environment

An experimental method using high temperature gas flow to simulate aerodynamic thermal environment of hypersonic vehicles is introduced. In the test section of the experiment equipment, a high temperature gas flow is ejected into room temperature air to make heat distribution of the experimental condition in line with that of the real flight condition on the cap. The gas flow and heating characteristics of the experimental equipment are simulated using CFD software FLUENT. Numerical simulation results verify of the experimental method and provide basis for further demonstration of high-temperature-gas thermal environment ground experiment facilities.
