Abstract:
In this paper, the lattice-Boltzmann method is used to investigate the droplet dynamics after impact on horizontal and inclined solid surface. The two-phase interparticle potential model is employed. The model is found to possess a linear relation between the macroscopic properties (surface tension σ and contact angle α) and microscopic parameters (G, Gt). The flow state of the droplet on the surface is analyzed in detail, and the effects of surface characteristic, impact velocity, impact angle, the viscosity and surface tension of the liquid are investigated, respectively. It is shown that the lattice-Boltzmann method can not only track exactly and automatically the interface, but also the simulation results have a good qualitative agreement with ones of the previous experimental and numerical studies.
Key words: Lattice-Boltzmann method interparticle potential model droplet impact two-phase fluid numerical simulation
