| Abstract: | Both moving coordinated method and finite volume method are used to simulate the flow caused by impulsively started and stopped cylinder. The evolution of vortices on the cylinder surface and the stream lines in flow are analyzed. This method can also be applied to simulate the flow field of a single object moving in unbounded fluid. |
