NUMERICAL SIMULATION OF QUASI-STATIC MODEL OF IONIC TRANSPORT THROUGH DEFORMABLE POROUS MEDIA
Original language description
The ionic transport in the charged porous media is problem studied in context of geoscience, research of fuel cells or modeling of biological tissues. This work, uses suitable mathematical models to simulate electroosmotic process in the porous media consisting of deformable solid phase with small electrical charge and the fluid phase in the pore space. The fluid phase is assumed to be an electrolyte solution of two ionic species with different valencies. It is possible to connect ionic transport not only with electrochemical phenomena, occurring due to the electric double layer formed by interaction between charged solid-fluid interface and ionized solution, but with mechanical behavior as well. The mathematical model describing this phenomena is treated by means of homogenization, resulting into upscaled model respecting material microstructure with stronger coupling between electrokinetic system and poroelasticity. Upscale model is then implemented in software SfePy. Numerical simulation are performed in order to simulate macroscopic behavior of upscaled model.
