Abstract

The Sanmeler, an impeller with asymmetric geometry developed by a Japanese company, can be used over a wide range Reynolds number from laminar to turbulent flow regions. Visualization of streak lines showed that their pattern spread quickly throughout the mixing vessel regardless of the liquid height, indicating that the Sanmeler had good mixing performance. The power consumption of the Sanmeler was correlated with simple modification of the correlations of other wide-paddle impellers.
