SIMPLE algorithm 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:...
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，使得数值求解N-S方...

In computational fluid dynamics (CFD), the SIMPLE algorithm is a widely used numerical procedure to solve the Navier–Stokes equations. SIMPLE is an acronym for Semi-Implicit Method for Pressure Linked Equations. The algorithm is iterative. The basic steps in the solution update are as follows: ...
A novel method in CFD derived from the SIMPLE algorithm is presented. Instead of solving the linear equations for each variable and the pressurecorrection equation separately in a so-called segregated manner, it relies on the solution of a linear system that comprises the discretisation of enthalpy...
