Multiphase/multicomponent systems have been widely applied in chemical engineering field

generally involving complex physical processes (such as species transfer

phase change

generation and movement of interface) as well as chemical reactions. It is of great challenge to model and simulate such complex systems. Lattice Boltzmann method (LBM) has attracted more and more attention as a relatively new method in recent years. Compared with traditional methods

multiphase/multicomponent lattice Boltzmann models have certain advantages

such as the convenience of tracking dynamic fluid interfaces and the easy definition of solid boundaries. It is an ideal approach for meso-scale and scale-bridging simulations

especially successful in the applications of fluid flow simulations involving interfacial dynamics and complex boundaries in the multiphase/multicomponent systems in micro-chemical engineering areas. Based on the methodology scheme of LBM

this review introduces the state-of-the-art development of LB models applied to simulate the gas-liquid and liquid-liquid micro-flow systems.
