EXPERIMENTAL RESEARCH FOR EHD ENHANCEMENT OF BOILING HEAT TRANSFER ON A HORIZONTAL TUBE

Keywords： heat transfer enhancement , boiling heat transfer , EHD

本研究对水平管外沸腾换热的EHD强化进行了试验,得出了沸腾换热系数与外加电场的电压、管壁热流密度等相关参数的关系,并对试验现象和外加电场的功耗进行了分析,为探索EHD强化沸腾传热的机理和理论以及它的工程应用提供了一定的依据。

EHD enhancement of boiling heat transfer on a horizontal tube was tested.Relation between heat transfer coefficients and related parameters such asvoltage of supplied electric field, heat flux on the tube was obtained.Analysis was conducted on the experimental phenomena and power consumption ofthe supplied electric field. The results have laid a foundation for exploringmechanism of EHD enhancement of boiling heat transfer and its practicalapplication in engineering.
