电场作用下水的粘性试验分析

电场作用下极性水分子和离子水化物将有序排列,由此导致水的粘度特性显著变化。文中通过室内试验,研究垂直于水流方向施加的电场对水的粘度特性的影响,在数字直流电源产生的强电场中进行常水头渗流试验,获得了水的粘度与电场强度关系的试验曲线,并观察在电场作用下,水的粘度与所含离子浓度、渗流速度等因素的关系,基于试验结果分析了电场改变水的粘度特性的作用机制。试验结果表明,外加电场对水的粘度有明显的影响,随着电场强度增加,水的粘度呈减小的趋势;在相同的电场强度下,水的粘度与离子浓度成正比关系,与渗流速度成反比关系。

Water's viscosity test analysis under the electric field

Water molecules and ions will be ordered arrangement hydrates under the electric field polar, which could change the water viscosity features.The effect of perpendicular electric field on the viscosity of the water was studied by laboratory experiment. The relationship curves between the experimental curve of electric field intensity were obtained by using constant head seepage and DC power supply system; the relationship between viscosity of water with ion concentration and flow velocity and other under the electric field was analyzed. The mechanism of water viscosity changing with electric field was detected basing the test results. The results show that the water viscosity is affected obviously by the electric field. The viscosi- ty of water s decrease along with the electric field sirength increase; Under the same field strength , the wa- ter is proportional to viscosity and ion concentration, and inversely proportional to flow rate.
