摘要：

The numerical results of mathematical modeling of a two-phase, axisymmetric swirling turbulent flow in the separation zone of a centrifugal separator are presented. Calculations were carried out for various turbulence models: Spalart-Allmaras rotation/curvature correction (SARC) and shear stress transport rotation/curvature correction (SST-RC) linear models, SSG/LRR-RSM-w2012 Reynolds stress nonlinear model, and the new two-fluid model. In the numerical solution the longitudinal-transverse implicit scheme is used where the pressure is coupled with flow velocity fields using the SIMPLEC procedure. The results from comparing numerical calculations against each other and against experimental data are presented.
