Abstract

A study of SA turbulence models in application to the calculation of swirling currents inside the separator has been carried out. The paper compared two approaches using vorticity and current functions to eliminate pressure and a semi-implicit method for pressure-binding SIMPLE to solve the Reynolds-averaged Navier-Stokes equations. For the numerical solution of both approaches, an implicit method against the flow was used.
