DeltaOmegaTildeDelta Class Reference

Delta formulation that accounts for the orientation of the vorticity vector. In "2D-regions" (i.e. xy-plane), delta is of the order max(delta_x,delta_y), so that the influence of delta_z is discarded. This can help to accelerate the transition from RANS to LES in hybrid RANS/LES simulations. More...

Detailed Description

Delta formulation that accounts for the orientation of the vorticity vector. In "2D-regions" (i.e. xy-plane), delta is of the order max(delta_x,delta_y), so that the influence of delta_z is discarded. This can help to accelerate the transition from RANS to LES in hybrid RANS/LES simulations.
