AB - In this study, a 2-D lattice Boltzmann method was used to numerically study the interaction between two light particles rising freely in a channel. The influence of the Reynolds number and the density difference between the particles as they rose was studied from the aspects of particle velocity, motion trajectory and motion pattern. The results show that a change of Reynolds number changed the relative position and distance between the particles, and a change in density changed the inertial force of the particles, which affected the interaction between them. Two movement patterns have been revealed: relatively static and a periodic movement pattern. The influence of differing density on the movement period of the particles was also studied.
