Evaluating Energy Efficiency of High-Speed and Hybrid Stirrers

Abstract

We have developed an experimental investigation procedure and have carried out a comprehensive analysis of the effect of the design and kinematic characteristics of high-speed and hybrid stirrers on the intensity and efficiency of mixing for liquid heterogeneous systems. We have shown that compared with the high-speed stirrer, the efficiency factor for the hybrid stirrer increases by 25% on the average. The intensity of mixing when using the hybrid stirrer increases compared with the high-speed stirrer, and this trend is enhanced as the speed (rpm) of the stirrer increases.
