Abstract
Employing two kinds of fine glass beads at low Reynolds numbers, the longitudinal dispersion coefficients of gas were measured in a moving bed by analyzing the response curves measured at two downstream points of a bed. The dispersion data obtained in a moving bed were comparable with the results investigated by Carberry and Bretton3) in a packed bed for Ihe same sysiem of helium-air. The effect of solid velocities on the gas mixing was not so favorable, and the concept of tortuosity factor was acceptable to describe the discrepancy of the data with the molecular diffusivity at low Reynolds numbers.
