在夹克衫试管热 exchanger 的水的传送对流热转移的 electrohydrodynamics (EHD ) 改进在这份报纸通过一个试验性的方法被学习。在实验，一个 DC 高电压电极被放在热 exchanger 的中央试管方面，并且在试管方面的高电压电极在 040 kV 的范围是可调节的。热转移改进实验的五不同联合在流动的不同电压和率下面被进行。当试管方面入口的流动率是 0.1 m3/h 时，结果显示最大的改进系数是 1.224。为水的工作媒介，对流的热转移能被使用高电场提高，这被证明。性能提高 EHD 对流动率的变化敏感，并且在那里在一样的流动评价存在在提高 EHD 的进程而非 monotonic 的优化电压积极关联的关系。

英文摘要：

The electrohydrodynamics （EHD） enhancement of convection heat transfer of water in a jacket tube heat exchanger was studied through an experimental method in this paper. In the experiment,a DC high voltage electrode was set in the central tube-side of the heat exchanger,and the high voltage electrode in the tube-side was adjustable in the range of 0-40 kV. Five differ-ent combinations of heat transfer enhancement experiments were conducted under the different voltage and rate of flow. The results indicate that the maximal enhancement coefficient θ is 1.224 when the flow rate of tube-side inlet is 0.1 m3/h. It is proved that,for the work medium of water,the convective heat transfer can be enhanced by applying high electric field. The performance of EHD-enhanced is sensitive to the variation of flow rate,and in the same flow rate,there exist an optimized voltage in the EHD-enhanced process ra-ther than the monotonic positive-correlation relationship.
