Modeling a Lid-Driven Cavity in COMSOL Multiphysics® The lid-driven cavity consists of a square cavity filled with fluid. At the top boundary, a tangential velocity is applied to drive the fluid flow in the cavity. The remaining three walls are defined as no-slip conditions; that is, the...

顶盖驱动空腔是计算流体力学(CFD)领域用于验证计算方法的常用问题之一。虽然涉及的边界条件相对简单,但是流动特性却相当复杂有趣。在本文中,我们将展示如何在 COMSOL Multiphysics® 软件中定义这一基准问题,并演示映射网格划分和非线性递增等适用于多种 CFD 模型的技巧。 在COMSOL Multiphysics® 中模拟顶盖驱动空腔 ...
Results are reported, in the case of the lid-driven cavity problem for Reynolds numbers in the range of 5000 < Re < 100000. As the Reynolds number increases, the time and the step mesh have to be refined, using a small step, both for time and space in order to capture the fast ...
