Abstract: Experiments on bed-to-surface heat transfer in the axial and radial directions were carried out in a cold flowmodel of the circulating fluidized bed of 244mm i.d.and with FCC catalysts(d_p=83.4μm)as the fluidized particles.A simplified gas-solid flow model comprising of the cluster-particulate phases upflowing cocurrentlywas proposed.By taking into account the alternative contacts of cluster and particulate phases with the immersedsurface,a composite heat transfer model was developed.The model gave good predictions as compared withthe experimental results of this work and those of others.
