摘要
为了提高混合效率,该文设计了一种小型的电磁动力驱动(MHD)混合器,对其混合特性进行了理论分析和实验研究。该混合器由聚碳酸脂和黄铜采用常规方法加工而成。研究液体为硫酸铜溶液,采用粒子图像测速技术进行实验,在实验过程中为观察溶液的流动混合搅拌过程,溶液中加入荧光粉作为示踪粒子,并通过数据采集和处理系统对实验结果进行分析,得到流场的速度分布。建立该混合器的理论模型,在实验的基础上进行数值模拟,并对结果进行分析比较,模拟结果与实验结果相吻合。
To improve the mixing efficiency,a minute magneto hydro dynamic（MHD）mixer is designed.The characteristics of the mixer are studied theoretically and experimentally.The mixer is fabricated with an ordinary brass and polycarbonate plate by the conventional machining method.The fluid used in the study is a bluestone solution.The particle image velocimetry technique is used in the experiment,and the fluorescent power is added into the solution to visualize the flowing and stirring.The experimental result is analyzed using the data acquisition and processing system.The velocity distribution of the flow field is obtained.The theoretical model of the mixer is established and a numerical simulation is done.The results are analyzed,being in good agreement with the experimental results.
