Abstract

The large eddy simulation method with mixture model is used to describe the inside two-phase flow of the oil - water separator. Then flow analyses of hydrocyclone field with different structures are compared by numerical simulation in the inside flow field of oil - water hydrocyclone. The result shows that the radial velocity along the column diameter increases from the wall to the axis and it reaches the maximum in a radial location. Then it decreases sharply. The axial pressure difference is the driving force, which makes heavy phase fluid water flow from the wall to the tail pipe outlet, while radial axial pressure difference makes light phase fluid oil accumulate in the center of the vortex tube. The axial pressure difference is the driving force, which makes heavy phase fluid water flow from the wall to the tail pipe outlet, while radial axial pressure difference makes light phase fluid oil accumulate in the center of the vortex tube. Therefore, flow field performance with double conical structure is better than that with the tube structure.
