Parallel computation of supersonic reactive flows with detailed chemistry including viscous and species diffusion effects

This paper presents parallel computations of high speed steady-state hydrogen/oxygen and hydrogen/air reactive flows. The governing equations for reactive flow in the absence of viscosity, thermal conductivity and species diffusion effects are solved using an explicit algorithm while treating the chemical source terms in a point-implicit manner. The convective upwind and split pressure scheme is used to provide necessary artificial dissipation without contaminating the solution. Results indicate excellent parallel speedups along with adequate resolution of the reaction zone in both 1D nozzle and axisymmetric test cases. (Author)
