Theoretical and experimental investigation of the liquid flow around a gas bubble
Abstract
The relation between the shape of gas bubbles and the flow pattern around them is studied in order to improve understanding of the interaction between the gas and liquid phases. The equilibrium shapes of the free surfaces of the bubbles in different liquids are numerically computed. The liquid flow in the region of single rising bubbles with terminal velocities and high Reynolds numbers is investigated. A theoretical model for the shape of the free surface of a gas bubble and the flow field around it is presented. The usefulness and applicability of this model is tested by comparing experimental and calculated results.
