We discuss the applicability of multiphase lattice Boltzmann method for the simulation of the drop
oscillation. We demonstrate that the simulation of the single drop excited to the first eigenmode does
follow Rayleigh formula. Simulations show no sensitivity to the number of the discrete velocities with
D3Q19 and D3Q27 representations of the distribution function in three dimensions. The boundaries do
influent the motion of the drop—division of the computational area by the even and the odd number of
cells comes out important and leads to symmetry violence. The second part of the chapter describes the
oscillations of the ensemble of three drops due to the excitation of the central drop in the first eigenmode.
The motion of the backdrops does strongly depend on the viscosity of the fluid. We provide future details
of simulations.
