Two-Dimensional Modelling Approach for Electrokinetic Water Transport in Unsaturated Kaolinite

Although electrokinetic treatments for soil remediation and ground improvement have gradually undergone significant experimental development, one of the most important physical phenomena has received very little attention in recent years. Electroosmotic flow, especially unsaturated conditions, not been simulated domains more than dimension. In present work, a modification M4EKR code was used to study water movement partially saturated soils under treatments. Two different configurations were studied: electrodes placed electrolyte wells directly inserted into soil, treatment started conditions both. Due unrestricted availability fluid first case, saturation is inevitable, but second only spatial redistribution content can be observed. A detailed analysis variety involving several showed that number electrodes, distance between them and, above all, ratio two magnitudes determines efficiency energy consumed process.
