The Wilcox 2006 stress-ω model (also referred to as WilcoxRSM-w2006) has been implemented in the NASA Langley Research Center code CFL3D, and used to study a variety of two-dimensional and three-dimensional configurations. It predicted a variety of basic cases reasonably well, including secondary flow in a supersonic rectangular duct. One- and two-equation turbulence models that employ the Boussinesq constitutive relation were unable to predict this secondary flow accurately because it is driven by normal turbulent-stress differences. For the NASA trapezoidal wing at high angles of attack, the WilcoxRSM-w2006 model predicted lower maximum lift than the experiment, similar to the results of a two-equation model. Presented as Paper 2014-0404 at the 52nd AIAA Aerospace Sciences Meeting, National Harbor, MD, 13-17 January 2014
