BLOWING FROM A POROUS CONE WITH A EMBEDDED SHOCK WAVE,
Abstract
Massive blowing from a porous cone in a supersonic flow is considered under the assumptions of inviscid, conical flow. The injection is assumed to be uniform, normal, and supersonic. This last assumption requires a straight shock wave in the injected-flow field. The numerically obtained solutions have two noteworthy features. First, the contact surface angle relative to the cone's axis decreases sharply when the embedded shock wave moves off the body. Second, it is possible to have a completely supersonic flow from the outer shock wave to the body, so that any upstream effect due to the presence of the cone's base is eliminated. Detailed solutions are presented and a model for the porous wall is used to relate the position of the embedded shock wave to freestream and plenum conditions. (Author)
