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.
