Numerical Computations of Turbulent Swirling Reacting Flows Using URANS and LES
Proceedings of the Joint Propulsion Conference and Exhibit

Abstract
Numerical studies of turbulent swirling reacting flows are performed using unsteady Reynolds-averaged Navier-Stokes (URANS) and large-eddy simulation (LES). The conserved scalar-mixture fraction-based thermo-chemical variables are described using the steady laminar flamelet model. The Favre-filtered scalars are obtained from the presumed beta probability density function (β-PDF) approach. The flow field exhibits upstream recirculation zone due to the bluff body and a downstream vortex breakdown region induced by the swirling flow. The URANS approach underpredicts the flow and combustion variables when compared to LES.
