本文提出了通过 Villermaux/Dushman 测试反应表征的不同混合器的混合效率的详细比较。考虑到层流中的简单混合关系，展示了如何获得理论混合时间以及如何将其与流动的雷诺数和每质量单位流体的比功率耗散等操作参数联系起来。实验和理论混合时间的比较表明，传输到流体的总机械功率中只有百分之几对混合有效。 (C) 2009 Elsevier Ltd. 保留所有权利。
The present paper proposes a detailed comparison of mixing efficiency of different mixers that have been characterized by the Villermaux/Dushman test reaction. Considering simple relations of mixing in laminar flow, it is shown how to obtain the theoretical mixing time and how to relate it with operating parameters as the Reynolds number of the flow and the specific power dissipation per mass unit of fluid. The comparison of the experimental and of the theoretical mixing times indicates that only a few percents of the total mechanical power transmitted to the fluid is effective for mixing.
