摘要：
The shock wave interference on transpiration cooling is investigated numerically based on the macro representative elementary volume (REV) scale analysis method. The flow field characteristics of the shock wave/transpiration boundary interaction are obtained. The results indicate that different coolants have significant influence on the cooling efficiency. The larger the specific heat capacity of the cooling media, the better the cooling effect can be achieved under the same blowing ratio condition. The incident shock wave interference can affect the pressure distribution on the material surface, leading to obvious transverse flow of the coolant inside the porous media. The redistribution of the coolant flow can remarkably reduce the cooling effect of the shock wave interference location with higher pressure. The shock wave can also enhance the mixing of the high temperature mainstream and cooling media, and the wall recovery temperature can increase accordingly, weakening the cooling performance obviously. © 2021, Editorial Dept. of JA.
