Both bubble coalescence and droplet separation are important physical phenomena in the natural world and a variety of process industries. This paper presents results of numerical simulation of behaviours of bubble coalescence and droplet separation. The velocity distribution functions of two particles are used in lattice Boltzmann equations. Based on the lattice Boltzmann method (LBM), both the phenomena of two rising bubbles coalescing in liquid and a liquid droplet break-up on wetting
