Description

<p>Although there are many papers of the mixing power consumption, there is no paper that quantitatively discusses an effect of surface roughness of impeller blades on power consumption. In this paper, authors experimentally verified the effect of surface roughness of mixing impeller on the power consumption by machining the surfaces of various impellers to mimic rust and material changes. As a result, the ratio of surface roughness and diameter of the impellers had no effect on the power consumption when ε/ d≤0.0125.</p>
