Abstract Scope In this study, we investigate ion transport behavior in a dual phase system influenced by distribution and shape variation of the phases. Charge transport is represented by Nernst-Planck equation in a finite element model developed using COMSOL Multiphysics. We use a mathematical model to generate normally distributed phases to be used as geometric domain representing the dual phase system. Shape variation is obtained by using different regular geometric shapes as the representative phases. Charge transport can occur by diffusion, migration and convection and driven by chemical or electric potential and velocity. This ion transport behavior study gives insight to different multiphase systems, i.e., ceramic separation membrane, ceramic waste form system for nuclear waste materials.
