Abstract
This paper describes the use of a transputer-based 8-electrode capacit ance tomography system for imaging gas bubbles in a fluidized bed in t he vicinity of an air distributor plate. The quantitative results show how the solid concentration distribution varies as a function of time for three different flow regimes: bubbling, slugging and the transiti on to turbulent. Bubble shape, length and coalescence can be observed.
