Abstract
Experiments were conducted to explore the effect of free area, orifice diameter and grid thickness on the rate of backflow of particles (leakage, weeping) through the multi-orifice distributor. Air was used as a fluidizing medium. Two sieved fractions of glass beads and ash particles of different shape and density were employed in the experiments. The measured rates of backflow were fitted by an empirical correlation with an accuracy of ±30%.
