Abstract
The oscillation phenomenon during droplet spreading on solid surface is studied. Simulations based on the lattice Boltzmann method with the mass processed by the volume of fluid show that the oscillation continues during the whole spreading process and the maximum oscillation value occurs at the initial phase. By observing the amplitude of droplet contour volume and liquid membrane velocity, the amplitude change is obtained. The influence of droplet characteristics on amplitude is studied. Simulated results show that the effect of kinematic viscosity on droplet oscillation is greater than that of droplet surface tension. The velocity vectors inside the droplet are also tracked to understand the oscillation.
