Abstract: “Hydrocyclones are compact devices employed mainly for solid-liquid separation. CaCO3 separation from a 1% v/v aqueous suspension using a 15 mm diameter Bradley mini-hydrocyclone was studied both numerically and experimentally. The aim of this study was to compare experimental data with those obtained numerically, using three different approaches: stationary, pseudo transient and transient. Pressure and tangential velocity profiles, pressure drops, flow ratios, reduced grade efficiency curves, reduced cut sizes and reduced total efficiencies were compared. The simulated results agree for transient and pseudo transient regimes, and there is a reasonable agreement when comparing numerical and experimental data.”
