Numerical Study on the Rising Motion of Bubbles near the Wall

Based on the volume of fluid method (VOF), rising characteristics bubbles in near-wall static water are studied. In this study, influence wall motion bubble was studied by changing distance wall, diameter bubble, arrangement and size ratio, etc. The is expressed as average swing amplitude “Z”-shaped when rises. study found that case a single surface has certain rise its degree affected diameter. more obvious. greater distance, less wall; double bubbles, interaction force between significantly than surface.
