摘　　要：以氟里昂（R11）为工质，采用交流电场对填充玻璃珠的水平套管进行了强化沸腾换热实验，比较了不同粒径的多孔质材料对换热强化效果的影响。结果表明：在低热通量区域，外加电场对多孔质层沸腾换热有进一步的强化作用，但随着热通量的增大换热强化效果明显降低，甚至恶化。Experimental studies have been made for theEHD enhanced boiling beat transfer of R11 in horizontal an-nular tube filled with glass beads. The results show in lowheat flux region, the boiling heat transfer coeffcient will begreatly enhanced by filling the annular tube with porousmedium, while with the increase of the heat flux, the en-hancement factor of boiling heat transfer will decrease.
