Abstract

The space-time conservation element and solution element (CE/SE) method originally developed for non-reacting flows is extended to accommodate finite-rate chemical kinetics for multi-component systems. The model directly treats the complete conservation equations of mass, momentum, energy, and species concentrations. A subtime-step integration technique is established to handle the stiff chemical source terms in the formulation. In addition, a local grid refinement algorithm within the framework of the CE/SE method is incorporated to enhance the flow resolution in areas of interest. The capability and accuracy of the resultant scheme are validated against several detonation problems, including shock-induced detonation with detailed chemical kinetics and multi-dimensional detonation initiation and propagation.
