Notice of RetractionOptimization design of the rocket launching facilities and the thermal protection

Based on fully hexahedral mesh and the k-e turbulence model, the computational fluid dynamics method was used to the numerical simulation. Different angle of the double-faced deflector and the thermal protection of the launching facilities were calculated. The pressure and temperature parameters were obtained and the result was compared and analyzed. The appropriate model was selected. The numerical calculation method and the results can be used to the engineering.
