Краткое описание

Non-isothermal Unsteady Reynolds Averaged Navier-Stokes (URANS) and Zonal k−l based Large Eddy Simulations (ZLES) for a complex geometry flow are presented. The URANS models investigated include a high Reynolds number Explicit Algebraic Stress Model (EASM) and a full Reynolds Stress Model (RSM). The results demonstrate that overall the ZLES perfoms slightly better than URANS for the flow field. However, for heat transfer predictions, curently ZLES does not perform well. This needs to be further explored.
