The conductivity method is used to determine the time course of blending (homogenisation) of miscible liquids in a pilot plant fully baffled mixing vessel, and a torquemeter is used for measuring the impeller power input in the same system. Four-blade and six-blade pitched blade impellers and three high efficiency axial flow impellers are tested for the given degree of homogeneity (98%). The experimental results and also the results of the authors' previous study, in accordance with the theoretical approach described in the literature, show that there is a universal relationship between the impeller power number and the dimensionless blending time, taking into consideration the impeller-to-vessel diameter ratio, independent of the geometry of the axial flow impeller but dependent on the degree of homogeneity. This relationship is found to be valid on a pilot plant scale under a turbulent flow regime of an agitated liquid.}, type={Artykuły / Articles}, title={A study on blending characteristics of axial flow impellers}, URL={http://www.czasopisma.pan.pl/Content/84632/PDF/07-paper-Fort.pdf}, doi={10.2478/v10176-011-0025-3}, keywords={axial flow impeller, pitched-blade impeller, turbulent flow, impeller power input, blending time}, }
