the loose coupling algorithm was applied to drive the iteration of the aeroheating and heat transfer analysis. Then
the coupling characteristics of aeroheating-temperature field were studied. The results show that
before radiative equilibrium
the errors of cold wall and radiative equilibrium aeroheating are +55.1% and -15.4% over actual aeroheating respectively
so coupling analysis for aeroheating-temperature field was required. As the local adiabatic wall temperature is not changed with time
the surface heat-transfer coefficient is a key parameter for coupling effect. Only two aeroheating calculations are needed during calculation of coupling aeroheating-temperature field with average heat convection coefficient
and the error of predicted wall temperature is less than 2.5%
thus highly improving the analysis efficiency of coupled aeroheating-temperature field.
