Název v původním jazyce

Quasi-static model of ionic transport through deformable porous media

Popis výsledku v původním jazyce

The ionic transport in the charged rigid porous media is widely studied problem, often in context of geoscience, research of fuel cells or modeling of biological tissues. The latest serves as motivation to this work, especially the modeling of electroosmotic process in the cortical bone, which consists of solid bone tissue with small electrical charge and the bone fluid in the small interconnected channels. As usual, the fluid phase is assumed to be an electrolyte solution of two ionic species with different valencies. By assuming solid-phase of porous medium to be deformable, 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.
