Data on the hydrodynamics and power consumption induced by modified anchor impellers in cylindrical tanks

Abstract

In the present paper, the data assembled concerning the stirring of a viscous Newtonian fluid in cylindrical and unbaffled tanks is disclosed. The stirring is ensured by close-clearance impellers rotating at low speeds. This is a comparative study between three modified geometries of anchor impellers aiming to enhance the fluid circulation in the whole vessel volume, and especially at the lower part of the vessel. The suggested geometrical configurations aim also to keep the energy consumption at its minimum. The data summarized here provides an additional knowledge for the best selection of stirrers for a specified industrial application.
