The axial distribution of solid holdup was investigated in a bubble column of 0.07 m in diameter and 4.25 m in height. The particle phase was glass beads of diameter 66, 118, 243, 465 or 1,300 μm. The effective slip velocity and the axial dispersion coefficient of the solid particles were evaluated in batch operation without solids feed and were correlated on the basis of mixing length theory. The equations obtained were applied to analyze axial profiles of particle concentration with a continuous feed of solids, and experimental data in the literature were simulated successfully over a wide range of solid concentration.
