摘　　要：在自行设计组装的基于朗肯循环的低温余热发电模型的基础上,以CFC11为工质,进行了介电流体的EHD强化凝结换热的实验研究,得出了不同温度下凝结换热系数,热流密度与外施电压之间的关系,并对外施电场的功耗进行了分析,为EHD冷凝强化换热理论研究的扩展提供了一定的依据.Low temperature waste heat power generation model on the base of Rankine - cycle is designed and constructed, and the experiment on EHD enhancement of condensation heat transfer of dielectric fluid are conducted. CFC11 is selected as the working fluid. Relation between condensation heat transfer coefficient, heat flux and applied voltage under the condition of the different temperature is obtained and analysis is conducted on the power consumption of the supplied electric field. The results are valuable to extend the theoretical investigation of EHD enhancement of condensation heat transfer.
