In this paper, the quality of unstructured grids generated by Delaunay Triangulation Method and Bubble Packing method is compared by the classical lid-driven square cavity flow solved by SIMPLE algorithm on collocated unstructured grid. The velocity distributions on vertical and horizontal center lines are in good agreement with bench mark, which shows that both of the two grids can be used in CFD.
