A survey of chemicallyreacting, compressible flows

The Navier Stokes equations can be modified to model multiphase and/or chemically reacting flows. These new equations are a set of convection diffusion equations with stiff source terms added on to model production and destruction of individual species in the mixture. These equations can be solved with TVD Runge Kutta schemes in time and ENO schemes in space (29). Since ENO is very time consuming, we also consider split schemes which only use ENO in complex regions of the flow. We consider both thermally perfect and calorically perfect gases.
