Study on the meniscus-induced motion of droplets and bubbles by a three-phase Lattice Boltzmann model

摘要

Graphical abstractDisplay OmittedHighlights?We study the meniscus-induced motion of droplets and bubbles by LBM.?Symmetry and relative density of a droplet interacting with gravity influence the motion.?Gravity may enhance the bubble motion towards the wall.AbstractIn contrast to typical applications of the pseudopotential Lattice Boltzmann model to two components, quantitative validations and applications for three-component Shan-Chen model are performed here. First, the qualitative and quantitative validations for the following three cases were performed, i.e., three-phase separation, meniscus-induced bubble movement, and the three-phase layered flow. A scheme to control the simulated contact angle of drop
