Abstract
The generation and rise of bubbles in gas-liquid-solid flow systems are investigated by employing a coupled discrete element model and volume of fluid method. The calculation results disclose that the existence of solid particles has an important effect on the formation of bubbles. The causes of these results are analyzed through a velocity vector diagram of the flows, and the factors affecting the detachment time of the first bubble are also investigated.
