Abstract

The space-time CE/SE method originally developed for non-reacting flows was extended to accommodate finite-rate chemical kinetics for multi-component systems. The complete conservation equations of mass, momentum, energy, and species concentrations were directly tackled, and a sub-time step technique was established to perform the time integration of stiff chemical source terms in the formulation. In addition, a local grid refinement technique in the framework of the CE/SE method was incorporated to enhance the flow resolution in areas of interest. The algorithm was tested against several detonation problems with detailed chemical kinetics.
