N2 - This paper describes a new Detached-Eddy Simulation (DES) model based on Wray-Agarwal eddy viscosity turbulence model with rotation and curvature correction (RC). This new model is validated against experimental data and DNS results for flow in a curved channel, U-turn duct, planar rotating channel, rotating backward-facing step and a serpentine channel. It is shown that in several complex flow test cases, the new DES model performs better than several RANS models with RC.
