Velocity Distribution in Filter Chamber of 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 permeation was measured by use of a fiber-optic laser velocimeter. The effects of the rotational speed of the disk and chamber dimensions on the flow pattern can be evaluated in terms of the ratio K of the tangential velocities of the core and the rotating disk. New empirical equations for K-value are presented and successfully correlate our data compared with the former equations.
