提出了一种计算不可压缩两相流的VOSET方法，该方法结合了VOF方法和US方法的优点和缺点。该方法采用VOF方法捕捉界面，既能保持质量守恒，又能克服LS方法质量不守恒的缺点。作者提出了一种迭代几何运算来计算界面附近的水平集函数Phi，它可以用来计算精确的曲率kappa和平滑界面附近不连续的物理量。利用水平集函数Phi，可以克服VOF方法曲率不准确和界面附近不连续物理量光滑性差的缺点。最后，将VOSET方法的计算结果与VOF和IS方法的计算结果进行了比较。(C)爱思唯尔有限公司出版的2009年。
A coupled volume-of-fluid and level set (VOSET) method, which combines the advantages and overcomes the disadvantages of VOF and US methods, is presented for computing incompressible two-phase flows. In this method VOF method is used to capture interfaces, which can conserve the mass and overcome the disadvantage of nonconservation of mass in LS method. An iterative geometric operation proposed by author is used to calculate the level set function phi near interfaces, which can be applied to compute the accurate curvature kappa and smooth the discontinuous physical quantities near interfaces. By using the level set function phi the disadvantages of VOF method, inaccuracy of curvature and bad smoothness of discontinuous physical quantities near interfaces, can be overcome. Finally the computing results made with VOSET method are compared with those made with VOF and IS methods. (C) 2009 Published by Elsevier Ltd.
