An experimental research of the efficiency of a fluid mechanical cleaning by a rotary filter

Abstract

The article deals with an experimental research on the efficiency of a fluid clarification from mechanical impurities in a rotary filter with a discrete perforated filtering baffle and a storage bin. The experiment was conducted at different combinations of Reynolds numbers, characterizing the intensity of the forced rotational and radial movement of the fluid. The possibility is shown of removing over 90% of particles with a size of less than 2.5 times the diameter of the filter baffle’s openings. The regression equation has been obtained for the dependence of the clearing performance parameter on the modes of liquid motions in the filtration area.
