Abstract

Two new parabolized Navier-Stokes (PNS) codes have been developed to compute the hypersonic flow of chemically reacting mixtures of perfect gases over simple geometries. Both the codes employ a noniterative, implicit, space-marching finite-difference method and solve the gas dynamic and chemical equations in a coupled manner. The conditions for well-posedness of the space-marching method of solution have been determined from an eigenvalue analysis of the governing equations. The first code is for two-dimensional/axisymmetric flow fields and the second code is for three-dimensional flow fields. These codes have been used to compute hypersonic laminar flow of chemically reacting air over wedges, and cones at angles of attack. The results of these computations are in excellent agreement with those of reacting boundary-layer calculations.
