Rotation and Curvature Correction Assessment for One-and Two-Equation Turbulence Models

Abstract

The rotation and curvature (RC) correction proposed by Spalart and Shur, as well as the RC correction proposed by Hellsten, have been implemented in the Wind code. Both models were applied to a subsonic flow in a U-turn duct and a high-speed ground/jet interaction. Both models performed well for the U-turn duct. The Spalart and Shur RC correction is more sophisticated and, therefore, more accurate, general, and computationally intensive than the RC correction proposed by Hellsten
