| Abstract: | In recent years,free surface tracking method attracts more and more interests of the researchers and several kinds of method have been presented.In this paper,the most representative three methods of VOF approach and three methods of Level Set approach will be studied by making comparison of each methods in terms of their precision and computational time consumed in two idealized calculation samples,one is a rotational flow field and the other is a shear flow field,respectively.The final results show that level set method,especially particle level set method,can more accurately capture the moving interface compared with VOF method. |
