Summary: | The testing of various turbulence models was conducted when calculating separated swirling flows. For burning simulation, a simple phenomenological model is presented. The model takes into account the gas swirling effect on the velocity of flame propagation. The developed technique is applied to the calculation of the burn-out of a lean mixture in model combustion chambers with three-tier swirlers. It is shown that the reversed organization of combustion with outside ignition is more efficient than the scheme with inside ignition. In the calculations, the mutual swirling of the flows behind the swirlers was varied and its effect on the burn-out rate of the mixture was considered. |
