Effect of Geometric Variations on Three-Dimensional Flow Separation in a Practical Scramjet Inlet

Three-dimensional simulations of a practical scramjet inlet is performed to study the shock-boundary layer interaction in the inlet duct. The cowl shock interacts with the boundary layers on the side wall and the opposite wall. Numerical simulations provide a detailed understanding of the complex three-dimensional flow separation and shock structure. Further, effect of the location and strength of expansion fans upstream of the shock impingement point is investigated. It is found that a careful placement of the expansion corners can limit the extent of the separation region significantly.
