Abstract
In the extraction and production of petroleum offshore some equipment are used to separate the liquid and gas phases of a two-phase flow in order to use electric submersible pumps. The existing pieces of equipment are generally oversized, which makes them harder to be installed and handled 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 to analyze the division of the liquid and gas mass flow rates and the development of the liquid film flow. The two-phase flow gets into the distributor by the inlets, tangentially positioned, and a vertical ascendant flow liquid film is formed, influenced by the action of the centrifugal and gravitational fields. The performance of division is numerically analyzed, regarding the mass flow rate in the outlets of the distribution system. For the resolution of the numerical simulations it was used the finite volume method based on finite element (ANSYS-CFX software 17.2), two fluids Eulerian-Eulerian inhomogeneous model and turbulence SST (Shear Stress Transport) model. For capturing the liquid-gas interface the compressive advection discretization scheme is used.
