Description

A multiphase Lattice Boltzmann free-energy model with two particle distribution functions is adopted in order to simulate a few kinds of bubble movements. The model itself is analyzed as well. Few problems were discovered during our simulations. Furthermore, an assumption was proposed to explain how buoyancy acts in the model according to the analysis of pressure field during the bubble rising. Based on the assumption, a proper method to introduce the buoyancy into Lattice Boltzmann free-energy model was proposed as well. (authors)
