Abstract: | A lattice Boltzmann method which can simulate droplet dynamics on partial wetting surface with large liquid-gas density ratio is proposed. The interaction between the fluid-fluid interface and the partial wetting wall is typically considered. Using the method, the dynamics of liquid drops on chemically heterogeneous surfaces are numerically simulated. The corresponding mechanisms including droplet spreading, break-up and migration on such surfaces are studied on the basis of droplet shapes, moving contact lines and velocity fields. |
