Oral:

In this work it was investigated how the flamelet combustion model coupled with collision distance algorithm for entertrainment games reproduces turbulent reacting flows. The wrinkling length scale of the flame is modeled as function of turbulent fluctuating velocity and the turbulent fluxes are amended in accordance with assigned porosities at the cell faces. The combustion and porosity models are implemented in the framework of an in house Fortran code that solves the full set of Navier-Stokes equations. Results are presented for non-reacting flows and reacting flows over a bluff body for Re=44,000 and Ka=1 (Reynolds and Karlovitz numbers, respectively). Comparison with experimental data leads to agreement of 85%.
