The Numerical Simulation of the Flow Field in the Underground Hydrocyclone

Abstract:

For preventing sand in underground oil, this paper structures a model of hydrocyclone with the inside cyclone and the outside one seriesing and describes how it works. By the TGrid procedures, the all of the hydrocyclone is meshed with the tetrahedral and the boundary conditions are determined. The methods of Three-dimensional numerical simulation in FLUENT are used to simulate the velocity field distribution, the pressure field distribution, the path lines of the separated medition characteristics of the separated medium and the phase distribution of the medium. The affect of the internal separated medition characteristics to the separated performance is analysed. Through the simulation, it is found that the spiral fin in the hydrocyclone can guide the fluid to produce a vortex flow to meet the purpose of separating the solid-liquid. There is no formation of the air column comparing with the conventional cyclone, so the internal flow field is more stable to conductive to the separation of the media. It provides a basis for the improvement of the cyclone.
