This paper focuses on the ability of Lattice Boltzmann Method (LBM) for simulating dynamical behavior of a droplet in two phase flows. For the present study, a proposed LBM for simulating immiscible two-phase flow (Reis and Phillips [9]) is employed. A recently developed method of wettability simulations at solid-fluid interfaces is applied into the present model. Several numerical studies are performed to investigate the characteristics of a droplet motion on a solid surface with different contact angles under shear flow. Results show that the present approach is capable of modeling two-phase flows especially in the case of dynamic interfaces.
