Abstract
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. All rights reserved.
