Abstract

The motion of two bubbles under gravity is numerically studied through the lattice Boltzmann method for the Eotvos number ranging from 1 to 12.The effects of Eotvos number on the bubble coalescence and rising velocity are investigated.It has been found that the uppermost bubble deforms the most because of the maximum drag.In addition, the averaged rising velocity of the bubbles is also studied in this work.
