Abstract

Direct numerical simulations can provide detailed understanding of micro-mechanics of individual particle collisions in the presence of liquid, which is crucial in wet granular flows in many industrial applications. In this work, a numerical model is developed for such detailed simulations of collision of a spherical particle on a wet surface. The model combines the immersed boundary method and the volume-of-fluid method supplemented with a contact model for the description of gas-liquid-solid contact line. Careful verifications of the model are conducted for droplet-wall as well as droplet-sphere contacts. Simulation results for normal collisions of a sphere on wet surfaces are reported, and compared with the corresponding experimental data.
