| Abstract: | For numerical simulation of hypersonic vehicle in steady flight, it is necessary to give appropriate wall temperature conditions to obtain accurate prediction results. Since the wall temperature characteristics of hypersonic vehicle in wind tunnel test and real flight at high altitude are significantly different, the selection of wall temperature conditions in numerical simulation under two different conditions needs to be studied in detail. Three dimensional Navier Stokes equations are solved by numerical simulation method, and the influence of wall temperature on aerodynamic performance and boundary layer characteristic parameters of HTV 2 hypersonic vehicle under wind tunnel test and high altitude flight conditions is studied. The results show that the influence of wall temperature on aerodynamic is different between wind tunnel test condition and high altitude flight condition, leading to different selection criteria of wall temperature conditions. |
