| 内容記述 | This paper gives the results of an experimental study on a separated-reattaching turbulent boundary layer flow downstream of a rearward-facing step placed in a uniform supersonic stream. With emphasis on detailed structure of the reverse flow in the fully separated region, the measurements are made on static pressure distributions across the viscous layer and velocity profiles of the reverse flow. It is shown that the static pressure is roughly uniform everywhere in the fully separated region just downstream of the step. In the recompression region, the pressure is not uniform across the upper portion of the viscous layer where the flow is supersonic, whereas it is nearly constant across the low speed zone close to the wall. Detailed examination reveals that, in the fully separated region where the static pressure is uniform, the local velocity profiles of the reverse flow are self-similar and can be expressed, irrespective of the step height, in a single curve in a reduced coordinates system. However, it is not yet known exactly whether the similarity can be valid even in the recompression region. | |||||||||
