针对施加直流高压电场的电水动力学(EHD)强化管外沸腾换热和EHD强化管内凝结换热两种换热方式,提出了3个同轴圆柱特征电极参数,分别与最小场强电极、最小电场力电极、最小能耗电极对应.分析了3个电极参数的几何特性,结果表明,电极直径的大小,在EHD强化相变换热中起重要作用.
In this paper, three coaxial cylindrical characteristic electrode parameters are proposed for EHD-enhanced boiling heat transfer outside the tube and EHD-enhanced condensation heat transfer inside the tube for the application of DC high voltage electric field, The minimum electric field force electrode and the minimum energy consumption electrode.The geometric characteristics of the three electrode parameters are analyzed.The results show that the size of the electrode diameter plays an important role in enhanced phase transition heat transfer of EHD.
