Outline
The coupled Level Set (LS) method algorithm of medium interface treatment was studied. Advantages and disadvantages of different methods in medium interface treatment process were given by comparing different solution of rotating flow and shearing flow, and the reason is analysed. Particle Level Set (PLS) method and Coupled Level Set and Volume of Fluid (CLSVOF) method are greatly improved in the conservation property of fluid compared on the pure LS through the contrast test. For PLS method, the LS interface can be corrected through reseeding and tracking the particle accurately. For CLSVOF method, the LS function can be reinitialized by reconstructing the interface and transporting the volume. In practical application, the CLSVOF method is more efficient and reasonable, since frequently reseeding will reduce the accuracy and tracking each particle requires more CPU memory for PLS method.
