Abstract
The application of scale-resolving turbulence representations in turbomachinery promises significantly improved predictions over the classical steady RANS approaches. The scale-resolving models available in the DLR solver for turbomachinery applications TRACE are presented and evaluated using three testcases, viz. a circularX cylinder mounted in a square channel, a 2D streamwise-periodic channel with one wall having hill-shaped features and a low-speed compressor cascade with a tip gap. Results are compared to RANS and URANS predictions and conclusions are drawn.
