摘要

The study is focused on the porous blunt nosecone transpiration cooling process under supersonic incoming flow conditions using a two-domain approach based on the preconditioned density-based algorithm. The protection mechanism of blunt nosecone transpiration cooling and the effects of coolant injection rate on transpiration cooling performance are discussed. Results indicate that the bowshock is pushed off the wall by coolant injection and the boundary layer becomes thicker. The effect becomes increasingly obvious with increasing injection rate. Transpiration cooling can protect the downstream noncooling wall. With increasing coolant injection rate, the increase in the cooling effect at the leading edge is larger than that at the noncooling area downstream. Transpiration cooling performs better and skin friction is reduced, but the pressure drop for porous domains increases.
