VELOCITY DISTRIBUTION IN FILTER CHAMBER O F A ROTATING-DISK DYNAMIC FILTER WITHOUT PERMEATION

To analyze the flow pattern in the filter chamber of a dynamic filter with a rotating disk, the velocity of Newtonian liquid flow without pe rmeation was measured by use of a fiber-optic laser velocimeter. The e ffects of the rotational speed of the disk and chamber dimensions on t he flow pattern can be evaluated in terms of the ratio K of the tangen tial velocities of the core and the rotating disk. New empirical equat ions for K-value are presented and successfully correlate our data com pared with the former equations.
