A computational facility for reacting flow science

Abstract

We discuss recent developments in the application of high-order adaptive mesh refinement constructions in reacting flow computations. We present results pertaining to the time integration of coupled diffusive-convective terms in this context using a stabilized explicit Runge-Kutta-Chebyshev scheme. We also discuss chemical model reduction strategies, with a focus on the utilization of computational singular perturbation theory for generation of simplified chemical models. Starting from a detailed chemical mechanism for methane-air combustion, we examine a posteriori errors in flame species computed with a range of simplified mechanisms corresponding to a varying degree of model reduction. © 2006 IOP Publishing Ltd.
