Numerical Study on Effect of Wall on Upwelling Flow

Abstract:

Numerical method is done on effect of wall on upwelling flow induced by air bubbler in a tank. It shows that: this reverse flow causes the increasing upwelling flow with height; when the bubbler distance to wall decreases, it is gradually only influenced at one side and then it affects the upwelling flow; the change of velocity is small in the region below bubbler. So the numerical method is helpful to describe the flow field as figures clearly and design bubbler devices in air-lift engineering applications.
