Improved two-equation k-omega turbulence models for aerodynamic flows [PDF]
, 1992 Two new versions of the k-omega two-equation turbulence model will be presented. The new Baseline (BSL) model is designed to give results similar to those of the original k-omega model of Wilcox, but without its strong dependency on arbitrary freestream ...
