WebbPISO and SIMPLE are standard CFD solvers for incom-pressible ﬂows and we followed [14, 27] in their implemen-tation. We used the ﬁnite volume method (FVM) to dis-cretize Navier-Stokes equations which are then solved iter-atively until convergence. This iterative procedure consists of a sequence of well-deﬁned steps. For example, PISO Webb(SIMPLE,SIMPLE+R,SIMPLE+C,PISO) 1 Rixin Yu 2024-04-25. 2.
