EE impeller (i.e., microcarrier full suspension was achieved at a very low rotational speed) compared to other studied axial impellers. Bustamante et al. [4 ] conducted a study in order to evaluate the shear rate generated by the Rushton impeller compared to an EE impeller in an aerated mixing tank for both Newtonian and non-Newtonian fluids.
The effect of impeller spacing on the double-impeller flow pattern and power consumption was investigated in the laminar region. As a result, the effect of impeller spacing on the flow pattern was described based on the ratio of impeller spacing to the impeller blade height. ...

For a single impeller, the poor liquid–liquid mixing efficiency was observed at positions away from the impeller, such as the top and bottom of the stirred tank. It was found that the double impeller could solve this …
The impeller diameter was varied in the pilot plant scale vessel to obtain the impeller diameter to tank diameter ratio equal to 0.25, 0.33 0.40, and 0.46. A single, double, or triple impeller on a common shaft was used during experiments. The impellers were of the same type in every section.
The predicted local kLa has been found higher in curved blade impeller than the Rushton impeller, whereas stirred tank with double impeller does not show variation due to low superficial gas velocity.

Stirred bioreactors are commonly used unit operations in the pharmaceutical industry. In this study, computational fluid dynamics (CFD) was used in order to analyze the influence of the impeller configuration (Segment–Segment and Segment–Rushton impeller configurations) and the impeller rotational speed (an operational parameter) on the …
When fitting a tank with an impeller, it is important to choose between axial and radial flow types. (See Flow Direction below for more information about flow.) Radial impellers — which typically have rectangular vanes — are used when the tank media is excessively viscous or consists of two immiscible materials. Radial flow impeller types ...
