Sažetak
A steady laminar flamelet model (SLFM), in conjunction with hybrid turbulence model (HTM), has been applied in computational fluid dynamics (CFD) simulation of a turbulent piloted jet diffusion flame – the Sandia flame D. Stationary flamelet profiles and appropriate probability density function (PDF) tables, according to presumed β -PDF shape, were created in pre-processor step by using CSC solver. For the combustion simulation itself the AVL’ s CFD solver SWIFT has been employed. The computed results were compared with available experimental data. The additional assessment of HTM has been performed by comparing its results with adequate k-e predictions. The superiority of HTM over k-e has been observed.
