Comparison of Different Grid Structures for the Hydrocyclone Flow Field Simulation

Abstract:

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.
