Abstract : The report develops finite difference techniques for computing with reasonable accuracy the static pressure field downstream of a strong shock wave, based on Navier-Stokes equations. The leading edge shock over a sharp flat plate in a Mach 20 uniform stream is treated as a specific example. Various analytic models have been studied for suggesting the proper approaches to various aspects of computational difficulties, the most important of which are the oscillatory extraneous component in the computed results.
