Abstract

Present work aimed to study the effect of inclination on hydrocyclone performance characteristics using both computational fluid dynamics technique (CFD) and experimental method. Water only and silica slurry experiments and the corresponding CFD simulations in a 3” hydrocyclone are carried out at various inclined positions (0-600) to the vertical plane. Two-phase simulations are carried out with Volume of Fluid (VOF) model coupled with LES turbulence model. Multiphase simulations are carried out with Algebraic Slip Mixture model modified with lift forces and Newtonian rheology model corrected with fines for various solids concentration. The analysis shows an increase in the cut-size, underflow solids percentage and a decrease in the water split with the inclination. Cross validation of inclined cyclone’s CFD air core data is attempted with Electrical Resistance Tomography (ERT) and High speed camera. Predicted efficiency curves are found in a close agreement with experiments for all the inclinations. Comparison of experimental and predicted flow data clearly follows the trend with the literature.
