The article numerically solves the problem of a swirling two-phase flow in a separator using the Menter model (SST) and Spalart-Allmaras (SA). The computational domain, which consists of coaxial cylinders and a conical part, is reduced to a rectangular shape by a change of coordinates. The stream function and vorticity of the flow are introduced, the first equation for which is solved by the upper relaxation method and the “upstream” scheme is used to solve the second of them. To describe the motion of solid particles with a low concentration, we use the Logrange approach.The numerical results of applying both turbulence models are compared.

The Stability

Abstract The Taylor-Couette flow between two rotating coaxial cylinders remains an ideal tool for understanding the mechanism of the transition from laminar to turbulent regime in rotating flow for the scientific community. We present for different Taylor numbers a set of three-dimensional numerical investigations of the stability and transition from Couette flow to Taylor vortex regime of a viscous incompressible fluid (liquid sodium) between two concentric cylinders with the inner one rotating and the outer one at rest. We seek the onset of the first instability and we compare the obtained results for different velocity rates. We calculate the corresponding Taylor number in order to show its effect on flow patterns and pressure field.

The steady flow of anomalous thermoviscous liquid between the coaxial cylinders is considered. The inner cylinder rotates at a constant angular velocity while the outer cylinder is at rest. On the basis of numerical experiment various flow regimes depending on the parameter of viscosity temperature dependence are found.
