Prediction of Initial Motion of a Gas Bubble in Liquids
Editor(s)
Sienz, Johann
Abstract
Numerical predictions are presented for the motion and distortion of a single gas bubble rising through the liquid. The computations were made with an implicit finite-difference procedure which solves the transient equations of motion throughout the bubble and the liquid, such that the free surface between the gas bubble and the liquid is not a boundary of the computational domain.The predictions compare well with the experimental results of others. Computations are presented for bubble sizes from 0.02 to 0.05 m radius and for bubbles of different gas densities rising in liquids of different densities. Surface tension effects are neglected.
