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. Far-field TKE and ...
一、简介BSL k-\omega 模型与SST k-\omega 模型是非常流行的两方程涡粘性模型,由Menter提出。该模型继承结合了两个模型的优点:在边界层附近应用 k-\omega 公式,使模型可以直接计算到粘性底层,进而使SST k-\ome…
RNG k-e model can be used for a wide variety of flow regimes. SST k-omega, which is a blend between regular k-omega and k-e, can also be accurately applied for a wide range of Re. Having said that, since you are working with a heat transfer problem, it is extremely important to...
既然k-omega 和k-epsilon 各有所长,那就把它们结合起来吧,于是一个更加适用的湍流模型就诞生了。1992年,NASA Ames 研究中心的Menter 博士提出了著名的k-omega SST 湍流模型,在omega 方程后面添加了一个交叉扩散项,这个交叉扩散项刚好就是k-omega 和k-epsilon 模型之间的差...
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

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）。
