Abstract

VOF and Eulerian model in the software of Fluent are separately used in two-dimensional simulation calculations for air bubbling in water by single hole. The simulation results are compared with experiment photos by high-speed camera, it’s obtained that gravity should be considered in using VOF model; at lower air speed, VOF model is more accurate to simulate the bubble formation, separation, upward motion and coalescence; the simulation results of Eulerian model have an obviously difference with the experimental ones at lower air speed, but it’s suitable to simulate bubbling process for air at higher speed.
