EHD 强化大空间光滑管外核沸腾换热实验研究

Experimental Studies for Enhancement of Nucleate Pool Boiling Heat Transfer outside Smooth Tube by EHD Effect

以氟里昂（Ｒ１１）为工质，对大空间光滑管外核沸腾的ＥＨＤ强化进行了实验研究，得到了在外加交流电场的条件下沸腾换热系数与电压、热通量、电极形式、数目、位置、形状等因素的相互关系．

Several fundamental experimental studies have been made for the enhancements of nucleate pool boiling heat transfer outside a smooth tube under EHD effect systematically. The working fluid used in the experiments is R11. Under the following conditions the EHD effects for the enhancements of heat transfer are investigated respectively: 1) voltage; 2) heat flux; 3) the form,number,position and shape of the electrodes. The reasonable results are availablle which are useful both for further studies and for pratical uses.
