Abstract
To clarify the axial liquid mixing characteristics in packed beds, measurements of the residence time curves in beds packed with glass beads of several diameters and 1/2″ ceramic Raschig rings were undertaken. The curves were analyzed by the side mixing model, proposed on the basis of photographic observation of the flow pattern in ordered packed beds and the fit between the curve of model and that of experiment. The parameters of the side pocket model which give the axial mixing characteristics in packed beds are volume fraction of side pocket part and side mixing factor. These two parameters are well correlated with Reynolds number and Galilei number over a wide flow rate range.
