一种抑制激波-边界层相互作用的新型无源被动控制
Investigation of a new-type passive control method on shock-wave/boundary layer interactions
摘要
Abstract
In order to explore a new-type passive control method to suppress shock-wave/boundary layer interac tions , passive controlling separation of two dimensional corner flow and shock impinging on flat plate were numerically simulated respectively with finite volume methods computational fluid dynamics code. The numerical results showed that the separation bubble of the two dimensional corner flow was eliminated completely with the passive method. For the separation induced by shock wave impinging on the flat plate, the separation bubble length was reduced to 58% , total pressure recovery coefficient increased 7.2% , and at x =85mm section the maximum velocity magnitude of in verse flow was reduced 69. 3% , in compared with the case without passive control applied. And the possibility of the passive control method in suppressing separation induced by shock-wave/boundary layer interaction was demonstrated.关键词
