The purpose of this thesis is to perform numerical solutions of hypersonic, high temperature, perfect gas flows over various geometries. Three dimensional, thin layer, compressible, Navier-Stokes equations are solved. An upwind finite difference approach with Lower Upper-Alternating Direction Implicit (LU-ADI) decomposition is used.
Solutions of laminar, hypersonic, high temperature, perfect gas flows over flat plate and compression corners (qw=5° / , 10° / , 14° / , 15° / , 16° / , 18° / and 24° / ) with eight different free-stream and wall conditions are presented and discussed. During the analysis, air viscosity is calculated from the Sutherland formula up to 1000° / K, for the temperature range between 1000 º / K and 5000 º / K a curve fit to the estimations of Svehla is applied.
The effects of Tw/T0 on heat transfer rates, surface pressure distributions and boundary layer characteristics are studied. The effects of corner angle (& / #952 / w) on strong shock wave/boundary layer interactions with extended separated regions are investigated. The obtained results are compared with the available experimental data, computational results, and theory.
