中文摘要：

目前，不可压缩两相流问题的数值求解方法主要有VOF方法和Levelset方法等．根据CLSVOF方法基本思想，通过将VOF和Level Set两种方法结合，实现了复合Level Set-VOF方法追踪不可压缩两相流相界面的模拟计算；对比分析了VOF、Levelset和复合Level Set-VOF方法计算经典两相流问题的结果．研究结果表明，复合Level Set—VOF方法继承了VOF方法精确构造相界面和LevelSet方法精确计算表面张力的优点，能够有效削弱两相流求解过程中出现的虚假流动问题，因此可以更加精确地求解不可压缩两相流问题．

英文摘要：

At present, the main methods of computing two-phase flows are VOF method and Level Set method. In this paper, the combined Level Set-VOF method used in the computation of incompressible two-phase flows was put forward based on the basic idea of CLSVOF method, and the computation results of some classical two-phase flows solved by VOF method, Level Set method and combined Level Set-VOF method were compared. The results show that the combined Level Set-VOF method inherits the advantage of VOF method namely precisely structuring phase interface, and that of Level Set method, namely accurately computing surface tension. The combined Level Set-VOF method can effectively weaken spurious current problems in the computation of two-phase flows and obtain more precise solutions to incompressible two-phase flow problems.
