摘要

Abstract

The size of initial bubbles is an important factor to the developed bubble size distribution in a gas-liquid contactor. A liquid cross-flow over a sparger can produce smaller bubbles

and hereby enhance the performance of contactor. A one stage model by balancing the forces acting on a growing bubble was developed to describe the formation of the bubble from an orifice exposed to liquid cross-flow. The prediction with this model agrees with the experimental data available in the literatures

and show that orifice size strongly affects the bubble size. It is showed that the shear-lift force

inertia force

surface tension force and buoyancy force are major forces

and a simplified mathematical model was developed

and the detachment bubble diameter can be predicted with accuracy of
