Turbulent flow fieht of dynamic hydrocyclone for oily wastewater separating was numerically simulated and its results show that the distribution of flow field is three dimensional and asymmetric. Also, the simulation results of axial and tangential velocity was basically consistent with experimental resuhs. The simulation of radial velocity will be helpful to analysis of the structure and performance of dynamic hydrocyclone for oily wastewater separating. The effect of pressure decreasing and inlet pressure on separation efficieney was indirectly embodied only by the change of rotation speed o...
