2004-5-1  The presented hydrocyclone CFD predictions have provided a novel understanding of the development of the initial flow field. Alongside the expected tangential velocity profile (`hat-type' vorticity, Alekseenko et al., 1999 )), novel predictions of asymmetry and of the transverse and axial velocity profiles have been obtained.

Basic Design of Hydrocyclone: [Essay Example], 768 words

2019-2-11  The conventional understanding is that particles within the hydrocyclone’s flow pattern are subjected to two opposing forces: an outward acting centrifugal force and an inwardly acting drag. The centrifugal force developed accelerates the settling rate of the particles, thereby separating particles according to size and specific gravity (and
