Integral Combustion Simulation of a Turbulent Reacting Flow in a Channel with Cross-Stream Injection

Abstract

A new integral one-step reaction submodel has been developed for an Argonne combustion computer code to simulate reacting flows of an advanced combustor for magnetohydrody-narmic power generation. The integral combustion code makes numerical calculations of a reacting flow more efficient and mart stable while still preserving the major physical effects of the complex combustion processes. Results of the simulation indicate that (1) fluid mixing is mainly responsible for combustion performance and (2) counterflow injection with an injection angle in the range of 120^° to 140^° yields the best mixing and combustion performance.
