VOF法与Level Set法的比较

VOF method and Level Set method is the popular technique of interface capturing ,with many similar aspects. In this paper,the two methods and their various schemes are introduced detailedly. At last, the two methods is applied in shearing flow, and the excellence and disadvantage of the two methods is analysed. The test show, VOF can induce some fragments that isn’t actual in physics with complex interface reconstructing.But some VOF shemes can simulate some sharp interfaces well than Level Set. Level Set needn’t reconstruct interface,and interface shape of simulatation is more smooth than VOF ,with better result.
