| 摘 要： | 利用EHD技术进行了工质R123的池内平板沸腾强化传热实验研究.在该实验中,换热面为一平板并接地作为0电极,高压电极为平行于换热面的网状电极.实验结果表明,正电压的强化效果较好,电压越高,强化效果越好.低热流密度下,EHD对沸腾换热的强化效果比高热流密度的强化效果好.起沸点随着电压的增加而增加,同不加电压时相比,在20 kV时,起沸点提高了4倍.

| Abstract: | The experiment study of EHD enhancement of pool boiling heat transfer from a horizontal plate with R123 was presented in this paper.A pair of parallel electrodes were used in this experiment, in which high voltage was applied on the upper straight net electrode while the lower heat transfer surface was earthed.Experimental results show that positive voltage brings better enhancement effects of heat transfer than negative voltage and the enhancement effects are improved with the increase of positive voltage.... |
