  • Abstract

    To enhance the ability of large eddy simulation (LES) to predict turbulent swirling flow, a subgrid eddy viscosity model based on the swirling-strength was applied to the LES of the non-reactive flow of the Sydney swirl burner. Two operation conditions， high Reynolds number with low swirl number and low Reynolds number with high swirl number, were selected to validate the performance of the proposed model in the strong shear layer and swirling flow, and the model simulation results were compared with the dynamic Smagorinsky model (DSM) and experimental results. The simulation results show that the LES results based on the swirling-strength model (SSM) can reasonably predict the important characteristics of the recirculation zone and precession motion of the central jet, which indicates the SSM model results of statistical moment are better than the DSM model results. However, the prediction of the RMS values at the shear layer of swirling flow is higher than experimental data, which indicates that the kinetic energy dissipation of SSM model may be over predicted in the shear layer, and that the SSM model needs to be improved in future.
