Research on flow field characteristics of dense medium cyclone with inclined medium inlet

To understand the effect of medium inlet on flow field of dense medium cyclone,the flow field characteristics of the equipment with inclined medium inlet is analyzed by PIV measuring and testing technique and CFD numerical simulation technique. The result shows that three-dimensional velocity inside the dense medium cyclone with inclined medium inlet is always higher than that inside the traditional one,which can save energy and reduce cost; and the best flow field is obtained at 85° agnle of inclination on medium inlet. It also can be reference for upgrading structure of dense medium cyclone.
