LARGE-SCALE ANALYSIS OF INTERACTIVE BEHAVIORS OF BUBBLES AND PARTICLES IN A LIQUID BY A COUPLED IMMERSED BOUNDARY AND VOF TECHNIQUE
RESUMO
A new approach for direct numerical simulation of three-phase (gas-liquid-solid) flows is proposed. Implementation of a moving rigid surface in a fluid is based on an immersed boundary/solid-object method developed by the present authors, and the gas-liquid interface is captured by the volume-of-fluid (VOF) method with an interface reconstruction scheme. The proposed coupling technique enables simulation of flow structures induced by both bubbles and particles of comparable size, including the flow pattern around the gas-liquid and solid-liquid interfaces. In a suspension of 1024 solid particles and a bubble, some typical behaviors of bubble-particle interaction and liquid flow pattern are captured. Detailed analysis on the motion of the falling particles suggests that the particle rotation is strongly influenced by the behaviors of the rising bubble, giving rise to a snap reversal of the rotating directions of the particles due to the flow induced by the bubble.
