    Abstract

    The flow pattern in a circulating fluidized bed (CFB) is characterized by clusters of particles. In the present study, the length scales of the variations in solids volume fraction were analyzed from a number of experiments carried out with Geldart B particles in a 2D CFB. Large length scales are typical for the bottom region above which more narrow dense clusters are common.
