Abstract
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–e model, the k–e RNG (ReNormalization Group) model, the k–e model corrected for the Richardson number Ri, and the k–ω model. It is shown that the distributions of the velocities and pressure in a hydrocyclone obtained with the k–e 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.
