Abstract

Large eddy simulations of a turbulent premixed jet flame in a confined chamber were conducted using the flamelet generated manifold technique. The scope of the present research is to investigate the effects of inflow boundary conditions in these simulations. To evaluate the effect of two kinds of inflow boundary conditions, the numerical solutions using those boundary conditions are compared with experimental results. Turbulent flow generated by the self-recycling boundary condition behaves in a more realistic way, while randomly distributed perturbation imposed on the inlet boundary immediately vanished due to the lack of the turbulence structure. Quantitative comparison between experimental and
computational results was carried out and analized.
