| Outline of Final Research Achievements |
We develop a new three-phase LBM combined the two-phase LBM and the IB-LBM for complex moving boundary flows of gas-liquid-solid mixtures. The algorithm of the method is a simple explicit form in Cartesian grid without solving the Poisson equation for pressure and is quite suitable for parallel computing. In order to validate the method, we apply the method to the simulations of the impact of a body on a free surface and a milk crown, and the calculated results of the impact force on the body, the splash of the free surface and the breakup into small droplets are in good agreement with existing experimental data.
