In this paper the technique of cross-correlating the void fractions de
rived from the transmission signals of two gamma-sources is used for t
he non-intrusive study of bubble phenomena in gas-solid fluidized beds
. Special attention is given to the optimization of this method with r
espect to the statistical uncertainty inherent to radioactive decay. E
xperiments in a 40 cm gas-solid fluidized bed illustrate that bubble v
elocity distributions can be obtained. (C) 1997 Elsevier Science Ltd.
