Abstract The work on salt ion drift in a solution driven by an external electric field in a duct is continued here. The formation of a diffuse layer at the sidewalls of the duct, where saltwater continuously flows, may cause the electric field in the fluid's bulk to diminish and thus, ions drift block. In the present article, the spatial distribution of the electric field is studied, and the conditions where electric field reduction is prevented. It is found that this is possible if the initial salt concentration is low, i.e. as a secondary desalination or water purification method. Moreover, as salt concentration increases, ion removal techniques from the sidewalls should be applied so as to avoid diminishing of the electric field.

海水淡化中盐离子运动引起的电场分布和扩散层厚度研究

摘要 这里继续研究由管道中的外电场驱动的溶液中盐离子漂移的研究。在盐水不断流动的管道侧壁形成扩散层，可能会导致流体主体中的电场减弱，从而阻止离子漂移。在本文中，研究了电场的空间分布，以及防止电场减弱的条件。发现如果初始盐浓度低，即作为二次脱盐或水净化方法，这是可能的。此外，随着盐浓度的增加，应应用从侧壁去除离子的技术，以避免电场减弱。
