In the CFD(computational fluid dynamics) study of hydrocyclones, the grid is a important factor to predicting the flow field. An attempt has been made in this study, in the same turbulence model and boundary conditions, three different structures of grid, the structured grid, the unstructured grid and the hybrid grid, are compared for the predictions of the axial, radial and tangential velocities. It has been observed that the memory space structured grid is large, and there are much number grid of the unstructured grid. The structured grid led to an improved turbulence field prediction and thereby to predict the velocity fields of single phase flow field more accurately. The unstructured grids is used to simulate the process of oil-water separation.

The internal structure and the working principle of gravity oil-water separator used for self-circulation well-flushing equipment were given. Based on CFD, the flow field was calculated and analyzed with partition plate settings. The influences on separation efficiency were analyzed, according to velocity vector diagrams and oil drop trajectory diagrams. The results show that the location of the primary partition plate is installed more reasonable, the efficiency of separation is more advantage. Also, the structure and size of the primary partition plate and the size of the auxiliary partition plate can influence the efficiency of oil-water separation regularly.

Tangential Inlet

An innovative axial hydrocyclone separator was designed in which a guide vane was installed to replace a conventional tangential inlet, potentially aggravating inlet turbulence. The characteristics of velocity distribution, concentration distribution, and pressure distribution inside the separator were obtained through the numerical simulation of the turbulent flow of oil and water. The results showed that the flow field presented good symmetry, which eliminated the eccentric turbulence phenomenon in the conventional hydrocyclone separators and was beneficial for the oil–water separation.

Aqueous crude oil often contains large amounts of produced water and heavy sediment, which seriously threats the safety of crude oil storage and transportation. Therefore, the proper design of crude oil tank drainage device is prerequisite for efficient purification of aqueous crude oil. In this work, the composition and physicochemical properties of crude oil samples were tested under the actual conditions encountered. Based on these data, an appropriate crude oil tank drainage device was developed using the principle of floating ball and multiphase flow. In addition, the flow field characteristics in the device were simulated and the contours and streamtraces of velocity magnitude at different nine moments were obtained. Meanwhile, the improvement of flow field characteristics after the addition of grids in crude oil tank drainage device was validated. These findings provide insights into the development of effective selection methods and serve as important references for oil-water separation process.

An oil/water separator with inlet component, perforated plates and coalesence internals was designed in this paper. The influence of the perforated plates on the flow field and the structures of coalesence component on the oil/water separation were simulated by commercial software FLUENT. The results show that the perforated plates can prevent turbulence and eliminate back-mixing flow effectively. And the flow field uniformity was the best,when the distance between the two plates was 140mm.The separator with inclined plates had the highest separation efficiency of the three structures.
