good for most flow-sheeting purposes, a CFD model was necessary to study the effect of flow structure with changes in geometry and flow rates. A number of CFD studies were carried out inside a hydrocyclone (Pericleous and Rhodes, 1986; Hsieh and Rajamani, 1991; Dyakowski and Williams, 1993; Malhotra et al., 1994; Rajamani and Devulapalli, 1994).

Flow in a Hydrocyclone - COMSOL Multiphysics
hydrocyclone are displayed in Figure 3. Figure 3: Pressure drop and in-plane streamlines in the xz- and yz-planes. The two jets mix in the inlet chamber, resulting in azimuthal pressure variations on the vortex core. For certain hydrocyclone designs, this may cause the vortex core to destabilize resulting in poor separation performance.
