Abstract

A 2D single-phase free surface tracking model using the Lattice Boltzmann method (LBM) is developed in this study. In contrast to the conventional multi-phase models, it is not necessary to simulate the motion of the gas phase using this LBM single-phase algorithm, and thus improves the computational efficiency without sacrificing the underlying physics. Based on Gunstensen's immiscible Lattice Boltzmann algorithm, a perturbation is added to the distribution functions of the interface cells for introducing the surface tension and wetting into the LBM single-phase model. Implementations of the model are demonstrated for simulations of droplet deformation under the surface tension effect and the droplet spreading on solid surface with various wetting properties. Simulation results show that the proposed model can generate a surface tension that is isotropic, and the model allows for continuous control of contact angles by varying the mass gradient at the wall boundary cells.
