绝缘液体流动时管道内壁电荷分布探究

Research on the Space Charges Distribution in the Pipe when Insulated Liquid Flows

研究了当绝缘液体在管道内流动时,由于液-固界面处偶电层的不对称分布,而在管道内壁出现的所谓扩散层;讨论了当扩散层厚度与毛细管道的半径相比不能忽略时,管道内壁空间电荷的分布情况,初步提出了绝缘液体在管道内流动时,偶电层内空间电荷分布的理论模型,为后续进一步开展相关的实验研究奠定了一定的理论基础.

When insulated liquid flows through pipe, diffuse layer would be generated due to the unsymmetrical distributed double-electric layer on the surface of liquid-solid. The article discusses the charge distribution in the circumstance that the diffuse layer thickness couldn＇t be ignored compared with the radii of capillary, and advances the model of space charges distribution, which established the foundation for further research in this research area.
