文摘

Bubble size distribution and bubble shape data are obtained and analyzed. A correlation between Eotvos number and the aspect ratio is obtained. Influence of gas velocities and sampling position on bubble parameters are investigated. Correlation for the bubble shape works critically in the conversion of CLD into BSD.
