Title

Lattice Boltzmann Simulation To Study Multiple Bubble Dynamics

Abstract

Lattice Boltzmann method (LBM) has been used in this study to understand the behavior of bubble motion and bubble coalescence in liquids. For a fully periodic domain, bubble dynamics and shape for a single bubble and multiple bubbles are dependent on Eotvos number, Reynolds number and Morton number. Drag coefficient for single bubble motion under buoyancy has been computed and compared with existing correlations provided in terms of the flow parameters. For multiple bubbles, the bubble dynamics is dictated by vortex pattern of the leading bubble, which allows the bubbles to coalesce. Such simulations have also been run for different configurations of the initial bubble distribution for both in-line and staggered bubble configuration to show the effect of vortex shedding on the oscillatory motion of the bubbles.
