Experimental studies were conducted in a vessel of diameter 0.634 m equipped with high-speed impellers (Rushton turbine, Smith turbine or A 315). The following operating parameters were changed: volumetric gas flow rate (expressed by superficial gas velocity), impeller speed, sucrose concentration and type of impeller. Based on the experiments results, impellers with a modified shape of blades, e.g. CD 6 or A 315, could be recommended for such gas-liquid systems. Power consumption was measured using strain gauge method. The results of gas holdup measurements have been approximated by an empirical relationship containing dimensionless numbers (Eq. (2)).}, type={Artykuły / Articles}, title={Hydrodynamic Characteristics of Mechanically Agitated Air - Aqueous Sucrose Solutions}, URL={http://www.czasopisma.pan.pl/Content/84931/PDF/07-paper-Cudak.pdf}, doi={10.2478/cpe-2014-0007}, keywords={agitated vessel, aqueous solutions of sucrose, gas hold-up, power consumption}, }
