Further accuracy verification of the 2D adaptive mesh refinement method by the benchmarks of lid-driven cavity flows

Year: 2024

Type: conference-paper

Abstract: The lid-driven cavity flow problem is a well-known test case in fluid dynamics for validating computational fluid dynamics (CFD) algorithms. Despite its geometrical simplicity, the liddriven cavity flow problem exhibits a complex flow regime, mainly due to the vortices formed in the centre and at the corners of the square domain. Consequently, this paper verifies the accuracy of a 2D adaptive mesh refinement (AMR) method in estimating the locations of the centre of vortices for a steady incompressible flow in a 2D lid-driven square cavity. We consider an initial coarse uniform grid mesh with a resolution of 20×20 and 50×50 for Reynolds number Re = 1000 and 2500, respectively and perform ten refinements. Our study reports the location of the centre of vortices obtained for Re = 1000 and 2500. The accuracy of the result is shown by comparing the coordinates of centres of vortices located by the AMR method with the corresponding benchmark results from four different literature.
