【Abstract】 Based on the lattice Boltzmann method and the level set method,the I.B model of two-phase flow is used to simulate the process of droplet translation,as well as the whole process of droplet free falling and the impact of droplet on the liquid surface.The calculated flow field by the LB model is very consistent to the physical mechanisms.The effectiveness and reliability of the model are demonstrated by the numerical examples.更多还原
