Abstract

Abstract

The bubble hydrodynamics characteristics such as the bubble rising velocity, bubble shape and drag coefficient was studied. The bubble was generated using a hemisphere cup to collect specific volume and released to the still water manually. The bubble motion was captured by high speed camera. The parameter was obtained by digital image process routines. The rising behaviors of bubble with different size in still water were investigated. The comparison with existed drag coefficient correlation indicated that Tomiyama was better than Ishii and Chawa. There were similarities for the shape for relative large bubble. The experimental result was beneficial to the basic understanding of the flow dynamics and interfacial exchange where relative large bubble existed.
