A lattice kinetic scheme for bubble flows.
A lattice kinetic scheme for two-phase immiscible fluids with large density ratios is presented. The difficulty in the treatment of large density ratio is resolved by using the projection method. The method can simulate two-phase fluid flows with a density ratio up to 1000. The method is applied to the simulation of many bubbles rising in a long square duct. The complicated unsteady structures of the interface and the velocity field can be simulated in a stable manner.
