Abstract
Boussinesq-type closures for the Reynolds Averaged Navier-Stokes (RANS) equations fail to correctly predict Reynolds stress components for flow over curved surfaces and flow in rotating fluids [2], [33]. Two classes of vortical correction (VC) model are discussed with respect to the improvements in the predictive capability of RANS they offer for flows where substantial streamline curvature/ rotation effects exist. The work is intended to improve the fidelity of vortical flow computations within the RANS/URANS modeling framework of the DLR TAU code.
