Description

Power consumption for an anchor impeller was measured over a wide range of Reynolds number from laminar to turbulent flow regions. In the laminar region, the power number of the anchor was reproduced by the correlations of Nagata and Kamei et al. by considering the anchor as a wide paddle impeller. In the turbulent region, it was reproduced by the correlation of Kamei et al. without correcting the parameters. If a large vortex was generated in a turbulent mixing vessel, the experimental values of power number were larger than correlation ones.
