Abstract
Bubble columns are liquid filled vertical tubes which are aerated—usually from the bottom. They are widely used in bio technology and chemical engineering, e.g., for yeast production and waste water treatment. Despite their widespread application, the flow phenomena in these apparatus is not yet fully understood. Velocity measurements are required for a better understanding of the fluid mechanics as well as for the development of mathematical models for the computational fluid dynamics (CFD)(Pfleger&Becker,2001,Dudukovic,Larachi,&Mills,1999). The problems of the current methods available for the measurement of the liquid velocity are briefly described below.
