The Advanced Turbulence Parameters dialog contains additional options for the K-omega model: Intelligent Wall Formulation The Intelligent Wall Formulation reduces the sensitivity of results to the level of mesh refinement along the wall. It is enabled by default for SST k-omega. ...
Naturally, the proposed methods allow the original SST model to be modified accurately and alleviate the free-stream dependency. Comparisons with the original SST k-omega model demonstrate that the newly developed alternatives to actual wall-distance usually improve the response of SST model to non-...

Hi I was reading in ANSYS help documentations that K-Omega is insensitive to Y+ calculations but that makes me ask how do you assess whether the near wall mesh is refined enough ? Is Y+ or Y* between 2 and 4.5 acceptable? Knowing that the viscous layer is between 0 to 5. Another ...
[摘要]基于k-omegaSST模型、结合多相流模型及流体体积自由水面捕捉技术对含收缩段 的明渠流进行了三维数值模拟。模拟所得的不同位置处的流速纵向分布曲线与实验数据基本 吻合,验证了该模型在含收缩段明渠流预测中的适用性。此外,利用该方法对流场的自由水面 线、竖直流速分量、压力分布、水平流场等特性进行了分析与总...
