A Rearward Facing Step in a Hypersonic Stream,

Abstract

An experimental investigation was conducted for hypersonic flow over a rearward-facing step. The inviscid dominated region around this configuration was investigated by the method of rotational characteristics. The recirculation region was described by a primary expansion angle for the dividing streamline. The calculated results were compared with the experimental measurements as the critical verification. This comparison exhibited a favorable substantiation for the present analysis. Static pressure distributions on the model surface and impact pressure surveys were presented along with visual observations. A study of the three-dimensional effects on the finite span 'two-dimensional' model is also presented. (Author)
