Abstract Hydrocyclone is a device for separating particles by centrifugal force from water which is a working fluid. Because of its advantages such as real-time separation and no moving part in it, it is used in numerous applications such as classifying, solids separation and concentration, etc. The objective of this study is to numerically characterize the particle separation efficiency by changing the design of hydrocyclone that operates at flow-rate of 1 LPM. To do so, we changed the diameter of the vortex finder and the length of the conical section, etc. The specific gravity of the injected particles is 1.25. The numerical analysis results showed that 5 μm particles or larger could be separated 100%. In addition, separation efficiency became enhanced when the design of hydrocyclone was changed. For instance, the efficiency was improved as the diameter of the vortex finder was decreased, but the flow rate of the purified working fluid was decreased. We will also present experimental data using the optimized hydrocyclone.
