Suspension of solids in stirred tanks - Comparison of different calculations. The suspension of solids in stirred tanks has been the subject of various investigations over the last three decades. Though many equations for the calculation of the critical impeller suspension speed were derived and published during this period of time no conclusive descriptions have been achieved. As a consequence, serious problems arose concerning the scaling-up of the mixer, since the various equations led to completely different designs. Over the last few years new physical models have been developed to improve on this point. These models aimed to reach a better description by considering the fluid-dynamic process more accurately. This survey presents the actual state of investigation by systematically comparing the results of the latest models. Careful consideration of the experimental conditions gave fairly consistent results. The decisive problem of the scale-up procedure, however, remains unsolved.
