Abstract
A three-dimensional oil-water 2-phase turbulent flow and separation process in a single-cone hydrocyclone is numerically simulated using FLUENT software. The Eulerian model of a multiphase flow and Reynolds-stress turbulence model are both applied to this simulation for general applications, concerning with phases with volumetric ratio over 10% and anisotropic turbulent flow dominated by swirling in the hydrocyclone. It is well shown in the simulation that how separation, aggregation and shift of oil and water proceed in a single-cone hydrocyclone. The current simulation is verified by comparing predicted and measured separation efficiency of the hydrocyclone.
