CFD analysis to study the effect of design variables on the particle cut size in hydrocyclones

摘要: The modification of hydrocyclone geometry changes the dynamics flow, so particle cut size is affected. Computational fluid was applied to predict classification according size. Fluent code used perform computer simulations for five different geometries using large eddy simulation and volume models. sensitivity computed modifications in evaluated by changing basic design variables, such as spigot diameter, vortex finder cone angle. results show that can be predicted geometric configuration a wide range slurry concentration with small degree error computational dynamics. attributed absence particle–particle fluid–particle interaction modeling. However, this assumption known valid only diluted slurries some regions within hydrocyclone. As soon particles enter system, most them are located walls, creating conditions main core more concentrated were therefore close experimental cut-size values. In all cases, successfully. Therefore, evaluation standard manipulate achieve desired becomes possible. © 2012 Curtin University Technology John Wiley & Sons, Ltd.
