摘要: A turbulent combustion model, Conditional Source-term Estimation (CSE) is applied to a non-premixed jet methane flame. The conditional chemical source terms are determined on the basis of first order closure and averaged species concentrations obtained by inverting an integral equation. Tikhonov method implemented for regularisation. Detailed chemistry tabulated using trajectory generated low-dimensional manifold method. Radiation due gaseous included. Reynolds Averaged Navier–Stokes calculations performed two different turbulence models. objectives paper (i) assessment impact main numerical parameters in CSE (ii) comparison predictions with available experimental data results from previous simulations selected number domains points each domain shown have significant if not appropriately....
