On the basis of numerous suspension measurements, correlations are proposed for calculating the just-suspended impeller speed for a standard pitched four-blade turbine and three types of hydrofoil impellers produced by TECHMIX for several particle sizes and for a wide range of particle concentrations. The suspension efficiency of the tested impellers is compared with the efficiency of a standard pitched blade turbine on the basis of the power consumption required for off-bottom suspension of solid particles. It is shown that the standard pitched blade turbine needs highest power consumption, i.e. it exhibits less efficiency for particle suspension than hydrofoil impellers produced by TECHMIX.}, type={Artykuły / Articles}, title={Effect of Impeller Shape on Solid Particle Suspension}, URL={http://journals.pan.pl/Content/84838/PDF/11-paper-Rieger.pdf}, doi={10.2478/cpe-2013-0012}, keywords={mixing, axial impeller, hydrofoil impeller, just-suspended impeller speed, electrochemical method}, }
