One-dimensional coupled model for large-deformation electroosmotic consolidation and heavy metal ion migration of silt

open access: yesYantu gongcheng xuebao, 2022
Dewatering and metal removal of silt can be obtained by applying electrokinetics. A coupled model for one-dimensional electroosmosis consolidation and ion migration, called ECT1, is proposed.

Space charge and soil ionization: an electro-kinetic approach

open access: yesIEEE Transactions on Dielectrics and Electrical Insulation, 2011
This paper proposes an electro-kinetic model of soil ionization for concentrated electrodes submitted to impulse currents. This approach allows a better understanding of the dynamic response of earth rods. Since current density attains a sufficient value around the electrode, ionization appears in the soil and produces a transient reduction of the ...
