Abstract
In this paper the technique of cross-correlating the void fractions derived from the transmission signals of two γ-sources is used for the non- intrusive study of bubble phenomena in gas-solid fluidized beds. Special attention is given to the optimization of this method with respect to the statistical uncertainty inherent to radioactive decay. Experiments in a 40 cm gas-solid fluidized bed illustrate that bubble velocity distributions can be obtained.
