The bubble size was observed to increase with height above the distributor and with increasing gas velocity above minimum fluidization. No affect of particle size on bubble size was ovserved, and increasing the number of holes per distributor only reduced bubble sizes within 300 mm of the grid. An expression proposed by Darton et al. for truly bubbling beds was found to be applicable for the fluidized bed operating with predominantly wall-affected bubbles.}, pages = {121--126}, title = {THE SIZE OF WALL-AFFECTED BUBBLES IN PILOT SCALE FLUIDIZED BEDS}, volume = {25}, year = {1983} }
