Effect of Roughness of Mixing Impeller Edge on Power Consumption

초록

Although there are many reports on the mixing power consumption, there are very few reports that quantitatively discuss the effect of impeller surface roughness on the power consumption. In the previous paper, the effect of surface roughness on the power consumption was experimentally verified by applying a process that simulated rust and material changes to the surface of impeller blades, and it was shown that the power consumption was not affected when the ratio of the height of the impeller surface roughness element to the impeller diameter was e/d<0.0125. In this paper, the roughness of impeller edge was further investigated. It was found that the roughness of impeller edge slightly increased the power consumption.
