The optimization was made taking into account mixing power and homogenization time for ribbon impellers with a different number of ribbons and width operating in a laminar motion for Newtonian fluid. Due to minimum mixing energy required to stir a unit volume of liquid the most efficient impeller appeared to be that with one ribbon of width equal to 0.1 to 0.15 of the mixing vessel diameter. Impellers with more than one ribbon needed much higher mixing power but did not increase significantly secondary circulation in the vessel. These impellers increased first of all primary circulation, i.e. they increased only circular motion of liquid in the vessel.}, type={Artykuły / Articles}, title={Optimization of geometric parameters of a ribbon impeller}, URL={http://ochroma.man.poznan.pl/Content/105888/PDF/12-paper-Kuncewicz%20Stelmach.pdf}, doi={10.1515/cpe-2017-0038}, keywords={mixing, laminar motion, ribbon impellers, optimization}, }
