SST k-omega model The SST k-ω turbulence model [Menter 1993] is atwo-equationeddy-viscositymodel which has become very popular. The shear stress transport (SST) formulation combines the best of two worlds. The use of a k-ω formulation in the inner parts of the boundary layer makes the...
The SST models provide a platform for additional extensions such as SAS and laminar-turbulence transition. Advanced Parameters The Advanced Turbulence Parameters dialog contains additional options for the K-omega model: Intelligent Wall Formulation The Intelligent Wall Formulation reduces the sensitivity of ...

SST(剪切应力传输模型, Shear Stress Transfer) 特点: SST k-ω模型和标准k-ω模型相似
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-...
时间步长过大。时间步长过长可能会造成时间段内，斜率变化较大，从而会造成数值解偏离真解。一般而言，对于显式方法要求在指定的时间步长内流体流动不能超过一个网格（库朗数限制）。
k-e model which is a high Reynolds number of k-e family. During my literature survey (correct me where I am wrong), I found that k-w is a low Reynolds number with enhanced wall treatment set as default. While SST k-w incorporates the quality of both the k-e and the k-w model ...

The flow is turbulent and i use the komegaSST model for the turbulence. i simulated the flow with different mesh resolutions (various y+). The y+ values i were 30, 50, 100, 150. Now the problem is that i calculated the pressure loss analytically and the OpenFOAM results aren't even...
