Transient Lattice Boltzmann Numerical Simulation during the Dewetting of Liquid Droplet on a Flat Surface

This study examines transient behavior during the dewetting of a liquid film on a flat surface under a static contact angle condition using the pseudo-potential Lattice Boltzmann Method (LBM). The dimensionless ratios of both height-to-radius thicknesses of 0.1 and 0.05 are considered. The transient...

description This study examines transient behavior during the dewetting of a liquid film on a flat surface under a static contact angle condition using the pseudo-potential Lattice Boltzmann Method (LBM). The dimensionless ratios of both height-to-radius thicknesses of 0.1 and 0.05 are considered. The transient process from a liquid film and the oscillation prior to the equilibrium droplet were posed. Both the inter-particles and the solid�fluid forces are also managed to investigate the oscillations of the budding droplets and their properties. Moreover, the horizontal and vertical transient processes are presented in dimensionless space and time. Two-dimensional (2D) simulations show that the dominant rim force affects the movement of the peripheral convex wave to the center. The interactive forces in the solid�liquid system and inertia of the liquid results in the dewetting process from the film layer, liquid droplet budding, oscillated droplet, and the equilibrium droplet. Thus, the dewetting process not only involves the force of inter-fluid particles but also the force of solid�liquid.
