Abstract:In this talk, we first present a thermodynamically consistent and conservative diffuse-interface model for complex gas-liquid-solid multiphase flows where a new free energy functional is introduced. Then, this model is further extended to the problems with phase change and heterogeneous reaction. Based on the developed diffuse-interface model, the fluid interface dynamics, the wetting property of the solid surface, and the heterogeneous reaction can be described simply. To test the present diffuse-interface model, we develop a lattice Boltzmann method and conduct some simulations of benchmark problems. It is found that the results are in good agreement with the analytical, numerical and experimental data. Finally, the present diffuse-interface lattice Boltzmann method is also adopted to study complex gas-liquid-solid flows, freezing processes, and chemical reactions in porous media.
