Abstract : A numerical algorithm is presented for the solution of the supersonic interacting turbulent boundary layer equations including separation effects. A representative eddy viscosity model is used to describe turbulent stress. Mach 3 cold wall flow up a compression ramp at (Re sub infinity) = 100,000 is used to demonstrate the fundamental technique. The numerical algorithm developed is a relaxation technique taylored after the implicit alternating direction method employed for boundary value partial differential equation systems. (Author)
