Abstract
In the petroleum industry equipment capable of separating the liquid and gas phases of two-phase flow are necessary, in order to use centrifugal pumps. The existing pieces of equipment are generally oversized, which makes them harder to be installed on the seabed. An alternative would be the use of smaller centrifugal separators. Thus, in this work, a numerical analysis of a distribution system is performed prior to the centrifugal separators which have a cyclonic chamber. In this system the two-phase flow gets into the chamber tangentially and a vertical ascendant flow liquid film is formed and it is influenced by the action of the centrifugal and gravitational fields. The performance of separation is analyzed, regarding the mass flow rate in the exits of the distribution system. For the numerical simulations the finite volume method based on finite element (ANSYS-CFX software 15.0) is used, apart from the models two fluids Eulerian-Eulerian inhomogeneous and turbulence SST (Shear Stress Transport). For capturing the liquid-gas interface the compressive advection discretization scheme is used.
