Swirling flows provide intensive mixing in a small volume in addition to flame stabilization by the formation of a central recirculation zone which back-circulates heat. A numerical study of unsteady isothermal flow in a pilot scale pulverized- fuel swirl combustor has been performed using the standard k epsilon turbulence model and Reynolds stress model (RSM). The objective of this work is to compare the numerical predictions of the two turbulence models. The precession is induced by a tangential inlet, for primary air, and guide vanes, for secondary air. A sequence of CFD solutions on...
