Description

The mean flow and energy consumption in vessels powered by hyperboloid stirrers wasinvestigated. The Newton number followed an inverse linear law for Reynolds numbers belowapproximately 200, which had values more than twice higher the corresponding Newton numberfor a standard Rushton turbine. At high Reynolds number flows the Power number variedbetween 0.5 for a D/T= 0.78 impeller to 0.95 for a D/T= 0.24 impeller, as compared to a valueof 5 for the standard Rushton stirrer, and to values of 0.31 and 1.58 for the Chemineer andProchem hydrofoils.
