Coalescence and break-up in dense bubbly flows

Abstract

A combined experimental and computational study has been performed on the effect of coalescence and breakup in bubbly flows. A pseudo-2D bubble column with a special needle sparger has been constructed to obtain well-defined inlet conditions at the gas distributor. An advanced digital image analysis technique has been developed to determine the Bubble Size Distribution (BSD) as a function of position and superficial gas velocity. Most experimental studies of the size distribution have thus far concentrated on bubbly flow at relatively low void fractions. In the present study the column is operated in the regime of dense bubbly flow, where the individual bubble or a cluster of bubbles can be characterized, leading to the construction of the size distribution.
