The authors also cover the fundamentals hydrodynamics of solid–fluid interaction with application to the fluids and suspensions flow of in circular pipelines and discusses the flow pattern in hydrocyclones from a fluid dynamics point of view. The physical design, the empirical, phenomenological and numerical hydrocyclone models are presented.

In this paper rules are given that enable hydrocyclones to be designed for any separation problem in which the size of the particles to be separated is known. Constructional details and items to be observed in designing a cyclone or cyclone battery are discussed. Finally the design method is illustrated by an example.

· The measurement of the velocity distribution in a hydrocyclone is the first step in predicting the flow pattern from a fluid mechanics perspective. The simplest approach is to use inviscid isochoric flows. The three-dimensional nature of the flow produces a secondary anisotropic flow near the entry region.

· The Hydrocyclone Efficiency Curves are affected by many operating factors such as feed density, apex and vortex sizes and feed pump pressure. These factors will cause your cyclone classification to operate correctly, in roping or spraying mode. Everyone knows or has seen an “Ideal Cyclone Efficiency Curve” VS an actual real life ...
