Supersonic Laminar Flow Reattachment and Redevelopment Behind a Two-Dimensional Rearward Facing Step

Abstract

A theoretical study of the flow recompression, reattachment, and redevelopment associated with a supersonic laminar isoenergetic flow past a back step was made. Based on an integral approach, the governing system of ordinary differential equations for such recompression and redevelopment processes was derived by introducing simplified flow models. The effect of finite initial boundary layer on the mixing process was taken into account. The system of equations for recompression was integrated with the base pressure and the starting location of recompression as parameters. These parameters were then determined through the conditions to be satisfied at the point of reattachment.
