Abstract
A numerical approach based on lattice Boltzmann method (LBM) coupled with immersed boundary method (IBM) is applied to investigate the three-dimensional (3D) coating process of a moving droplet against a moving particle. Particle-droplet size ratio (2/15 ≤ α ≤ 2/3), Weber number (6.845 ≤ We ≤ 171.114) as well as collision factor (0 ≤ B ≤ 1.0) on the coating processes are taken into account. According to present simulation, three regimes are identified: full coating, partial coating, and disintegration. Moreover, the partial coating regime can be divided into two sub-regimes according to Weber number. And the disintegration regime also has two sub-regimes, depending on Weber number. The coating outcomes are summarized and the regime maps (We-α and B-α) are presented. The findings learned from this work can provide guides for many industrial applications.
