Abstract : Numerical solutions to the viscous shock layer equations are presented for hypersonic flow past hyperboloids opening to asymptotic total interior angles of 45 degrees and 20 degrees. Solutions were obtained using a modified form of the conventional alternating direction implicit approach which uses a time dependent iterative relaxation process for determining the bow shock shape. Solutions were obtained to the full shock layer equations as well as their thin shock layer approximations for Mach numbers M = 10 and 21.75, free stream Reynolds numbers, Re, of 430 and 64000 and wall to stagnation temperature ratios of 0.05 and 0.9.
