Delaunay Belleville was a well known automobile manufacturer in France at the time that tried to make some money in guns, but never really took off.

德劳贝尔维尔是法国知名的汽车当时是试图使一些钱，在枪支制造商，但从来没有真正起飞。

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.
