SIMPLE及PISO算法是CFD软件求解N-S方程中常见的压力-速度耦合方式，用于处理流动问题中的复杂性。N-S方程包括连续性方程及Ux、Uy、Uz动量方程，涉及Ux、Uy、Uz、p四个未知数，但并未包含直接求解压力p的方程。连续性方程实质上是动量方程的限制条件，且动量方程本身包含非线性对流项，使得数

交错网格 与交错网格相对的是同位网格,再RC插值方法提出之前,压力、速度都存于同一套网格中,共用网格节点。例如x方向的压力梯度项采用中心差分格式: ∂P∂x=PE−PW2δx 并没有使用到中心节点PC的值,而在棋盘振荡的压力场时,很容易被认为是无压力梯度,即均匀压力场。造成脱离真实物理的情况。因此交错网格被...

I have intended MRF SimpleFoam with K-w SST simulations with a wall-modelled approach (30<y+<300), the same with a wall-resolved method (y+ approx. 1) and also Sliding Mesh approach, as I was worried that the differences were due to the 'false swirl' effect...
SIMPLE [Semi-Implicit Method for Pressure-Linked Equations] If a steady-state problem is being solved iteratively, it is not necessary to fully resolve the linear pressure-velocity coupling, as the changes between consecutive solutions are no longer small. The SIMPLE algorithm: ...
