## Abstract Although axial liquid dispersion has been studied extensively in particulate fluidized beds, no data has been reported previously in a liquid–solid circulating fluidized bed (LSCFb). In this work, the axial liquid dispersions at various radial positions were measured in an LSCFB of 76 m

A phenomenological model of axial solids mixing in a circulating fluidized bed is formulated. The model allows for main specific features of the process: ascending motion of particles in the core zone and their descending motion in the annular zone (inner circulation of solids); substantial changes
Liquid-solid circulating fluidized beds have a number of attractive features suitable for processes where liquid-solid contact is important (Liang et al., 1996;Zhang et al., 2002). Liang et al. (1996) and Zheng et al. (2002) studied the radial profile of the solid fraction in the liquid-solid circul
Electrical conductivity probes were used to measure the radial distributions of solids holdup and liquid velocity in a liquid-solid circulating fluidized bed. These distributions are found to be non-uniform, unlike those in a non-circulating bed. The effects of superficial liquid velocity and partic
