This paper describes a review of the numerical simulations of multiphase fluid flow by the lattice Boltzmann method (LBM), in which a macroscopic fluid consists of mesoscopic particles repeating collisions and translations. One of the advantages is that an interface can be reproduced in a self-organizing way by repulsive interaction between particles. Two- and three-dimensional LBM simulation results are presented, spontaneous phase separation, deformation of bubble due to shear stress, and single- and two-bubble motions in a tube under gravity.
