A numerical investigation of the structure of the flow 
in a hydrocyclone has been carried out on the basis of Reynolds equations 
with the use of various models of turbulence: the k- model, the k- RNG 
(ReNormalization Group) model, the k- model corrected for the Richardson 
number Ri, and the k-model. It is shown that the distributions of the 
velocities and pressure in a hydrocyclone obtained with the k- Ri model, 
in which the influence of the rotation of the flow on the processes of 
generation/dissipation of turbulence and the anisotropy of the turbulent 
pulsations are taken into account, coincide most closely with the 
experimental ones.
