Photographic Fluid Velocity Measurement in a Hydrocyclone

Abstract

<p>The three dimensional flow patterns in a 3 inch diameter hydrocyclone operating without an air core were studied usina tracer particles and high speed cine photography. The cyclone was constructed and operated according to present design criteria for the optimum separation of Liquid-solid mixtures. Both cyclone geometry and operating conditions were the same throughout al I experiments analysis of fi Ims posed at 55 locations inside the hydrocyclone provided data for 18 velocity profi les which described the three dimensional flow in the hydrocyclone. This data was then checked for consistency by material balance considerations and compared with the results of earlier investigators who operated their cyclones with air cores.</p>
