Abstract:

An efficient numerical solution algorithm is presented for solving the interacting supersonic laminar boundary layer problem. The method employs a time dependent approach with the alternating direction implicit ADI scheme and directly accounts for the necessary downstream boundary condition. Solutions are presented for M sub infinity 3 cold wall boundary layer flow over a family of expansion and compression ramps including several cases with regions of reverse flow. Good comparison is given with experimental data and Navier Stokes solutions for M sub infinity 4, adiabatic wall, separated flow up a ten degree compression ramp. Author
