Description of the numerical methodology for the ercoftac test case F3

Abstract

Abstract: The purpose of this work is to compare different low-Reynolds-number turbulence models and their suitability for the highly three dimensional return channel with a deswirl cascade. A comparison is made between Chien's k-ε model, Chien's model with a rotational correction, Gatski et al. ARSM and the full Reynolds stress model by Speziale et al. Experiments are provided by Concepts ETI.

Main result: Results for the test case F3 in the ERCOFTAC Workshop on Turbomachinery Flow Predictions VI.
