Collision dynamics of particles and bubbles in gravity‐driven flotation: A DNS investigation
Abstract: This paper presents a numerical method to study the collision process of mineral particles and air bubbles in flotation cells. A bubble‐resolved and particle‐modelled direct numerical simulation was performed to study the particle–bubble collision frequency for representative flotation conditions. The location of the particle collisions on the bubble surface and the particle concentration around a bubble are investigated.
