In the present paper, the deformation and breakup of falling multi-drops is simulated using Lattice Boltzmann method. The effect of Eotvos and Ohnesorge number on different modes of deformation and breakup of the drops is considered. The results show that for all cases, the rate of deformation of drop at high Eotvos number is more than low Eotvos number because at high Eotvos number, the magnitude of the surface tension force to gravitational forces is small. Also the effect of wall on deformation, rotation and repulsion has been considered.
