This paper presents an improved method for inclusion of system rotation and streamline curvature effects into existing twoequation\r\neddy-viscosity turbulence models. A new formulation for calculation of the turbulence viscosity coefficient, which is\r\nimplemented into the traditional K-E model with a two-layer near-wall treatment in a commercial computational fluid dynamics\r\nsolver, is proposed. In contrast to precious model, the modi??ed rotation rate which appears in the formulation for turbulent viscosity\r\ncoefficient is herein expressed exactly and universally. Thus, it provides an effective alternative for turbulence modeling.
