The measurement of the velocity distribution in a hydrocyclone is the first step in predicting the flow pattern from a fluid mechanic point of view. The simplest approach is to use inviscid isochoric flows. The three dimensional nature of the flow produces a secondary an-isotropic flow near the entry region.
