Abstract

Upwind residual distribution schemes have been developed for the numerical simulation of inviscid flows of arbitrary mixtures of thermally perfect gases in chemical non-eqüilibrium. First, a multidimensional conservative linearization of the Euler equations for gas mixtures is derived. Then, a transformation to a set of symmetrizing variables is defined, which decouples the flow equations into n_s scalar advection equations and a coupled 3x3 system. Various alternative discretizations of the source terms are presented. Preliminary numerical resuls are presented which illustrate the applicability of the method to non-reacting and reacting flows.
