Abstract:The heat distribution on the surface of the blunt body is calculated using CFD method and compared with the experimental data to verify the reliability of the CFD methods. The temperature distribution inside the structure at different times is calculated using iterative coupled calculation and one-way solving methods respectively. The iterative coupled calculation completes the integrated calculation through the mutual data exchange between the flow field and the structure in single time iteration. The one-way solution obtains the aerodynamic heating of the surface through CFD method, and then obtains the internal temperature distribution through solving the Structure Heat Transfer Equation. The calculation results show that the stagnation point of the blunt body is the most seriously affected by the aerodynamic heating; the structural temperature calculated by iterative coupling calculation method is much closer to the experimental results than the one-way solution method.
