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模型之间的差异,而Menter博士则聪明的在这个交叉扩散项上面乘了一个混合函数,通过混合函数则可以轻易的控制湍流模型的变身:当混合函数为1时,omega方程还是omega方程...

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）。
SIMPLE(Semi-ImplicitMethodforPressure-LinkedEquations)算法是一种常 用的迭代求解策略,它将压力和速度的求解耦合起来。在燃烧仿真中,SIMPLE 算法可以与k-ω模型结合使用,以求解流场和湍流参数。 4.2.2.1简化示例代码 #假设我们有以下变量:k,omega,rho,u,v,p,nu,nu_t,G_k,phi_k,beta_star ...

请教Openfoam..openfoam小白,有偿请教,有意者请私我。问题:模拟流体漫过梁桥目前用interfoam作为solver,turbulence model是komegaSST涉及到multiphase,也就是液相
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
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 ...
