Pengtao Yue - Particle-bubble interaction is an important process in flotation. When a particle approaches a bubble, the bubble deforms and a liquid film may form between the particle and the bubble. Followed by the film drainage process, the particle may attach to the bubble or bounce back. If the particle attaches to the bubble, the problem is further complicated by moving contact lines. The whole process is very complicated and still far from a complete understanding. In this work, we calculate the problem by direct numerical simulation, intending to provide flow details that are difficult to obtain in experiments. A finite element-based arbitrary-Lagrangian-Eulerian method is used to track the moving boundaries of bubbles and particles. In this animation, we show the interaction between three falling particles and three rising gas bubbles in water. Pressure contours and velocity vectors are also plotted.
