A predictive model to probe the impact of gravity and surface tension on rising wetting thin films
journal contribution
posted on 2019-08-21, 00:00 authored by Zhen Luo, Shafigh MehraeenUtilizing kinetic Monte Carlo simulations, we developed a three dimensional Ising lattice gas model to reveal the wetting mechanism of a liquid film rising along a vertical substrate. The model takes into account the impact of surface tension, gravity, interaction energy between liquid particles, and between liquid and substrate on the rise of the liquid film. We verify that in low gravitational acceleration regime, the growth of the liquid film follows the universal law of √ t. As gravitational acceleration and surface tension vary, the simulation results show the detailed dynamics of the solid-liquid interface. Explicit analysis of the interface displacement and roughness under different gravitational accelerations and surface tensions is also presented.
