Abstract EN
The motion of multiple bubbles under gravity in two dimensions is numerically studied through the lattice Boltzmann method for the Eotvos number ranging from 1 to 12.
Two kinds of initial arrangement are taken into account: vertical and horizontal arrangement.
In both cases the effects of Eotvos number on the bubble coalescence and rising velocity are investigated.
For the vertical arrangement, it has been found that the coalescence pattern is similar.
The first coalescence always takes place between the two uppermost bubbles.
And the last coalescence always takes place between the coalesced bubble and the bottommost bubble.
For four bubbles in a horizontal arrangement, the outermost bubbles travel into the wake of the middle bubbles in all cases, which allows the bubbles to coalesce.
The coalescence pattern is more complex for the case of eight bubbles, which strongly depends on the Eotvos number.
