Abstract

The tip-leakage ow of a low speed compressor cascade at Ma = 0.07 and Re = 400,000 was simulated employing the Jakirli�c/Hanjali�c-wh (JH-wh) differential Reynolds Stress model (DRSM) and results are presented. The predictions are compared with those obtained using the SSG/LRR-w DRSM and the Menter SST k-w linear eddy viscosity model (LEVM). In addition to the mean flow quantities, the focus is on the Reynolds stresses and their anisotropy. Both DRSMs show significant improvements compared to the LEVM with respect to the mean flow quantities; however, details of the turbulence structure are more accurately predicted by the JH-wh model.
