Abstract
A new approach for direct numerical simulation of three-phase (gas-liquid-solid) flows is proposed. Implementation of moving rigid surface in a fluid is based on an immersed boundary/solid-object method method developed by the present authors, and gas-liquid interface is captured by volume-of-fluid (VOF) method with an interface reconstruction scheme. The proposed coupling technique enables simulation of flow structures induced by both bubble and particle of comparable sizes, including the flow pattern around the gas-liquid and solid-liquid interfaces. In a suspension of 1024 solid particles and a bubble, some typical behaviours of bubble-particle interaction and liquid flow pattern are captured. The detailed analysis on the motion of the falling particles suggests that the particle rotation is strongly influenced by the behaviours of the rising bubble, giving rise a snap reversal of the rotating directions of the particles due to the flow induced by the bubble.
