Abstract

In this study, the operational parameters of the micro-cyclone were investigated. A 10 mm micro-cyclone suitable for waste drilling mud treatment was designed and the effect of the inlet on the flow field within the micro-cyclone as well as the total separation efficiency was investigated using CFD techniques. It was concluded that the pressure gradient inside the micro-cyclone increased with increasing inlet flow; axial and tangential velocities increased with increasing inlet flow; the peak turbulent kinetic energy increased with increasing inlet flow; and the total separation efficiency increased and then decreased slightly with increasing inlet flow.
