Computation of Three-Dimensional Supersonic Viscous Flows in Internal Corners.

Abstract

Three-dimensional, supersonic viscous flows in internal corners are computed by solving the unsteady Navier-Stokes equations subject to a local conical assumption. These governing equations are solved using MacCormack's explicit finite-difference scheme. A generalized coordinate system is employed which permits the grid to be refined near walls as well as in interaction regions so that viscous details can be properly resolved. Both shock fitting and shock capturing techniques are used. Two different corner flowfields are computed and the results are compared with experimental data and previous numerical solutions of the complete Navier-Stokes equations. (Author)
