A subgrid-scale model for the scalar dissipation rate in nonpremixed combustion

A subgrid-scale model is discussed for the scalar dissipation rate in nonpremixed turbulent reacting flows. The model contains a coefficient which is determined by assuming a form for the scalar energy spectrum. The model is tested a priori using Direct Numerical Simulation (DNS) results for a temporal reacting mixing layer. The estimated dissipation rates are in good agreement with dissipation rates computed directly from the DNS data. Furthermore, the assumed spectrum methodology is found to accurately predict the model coefficient, including its spatial and temporal variations.
