Experimental study and mathematical model of nanoparticle transport in porous media

Mathematical model and experiment on suffosion/clogging process are presented. The model is based on the theory of flow in deformable porous media with mass-variable skeleton. It is shown that clogging occurs at a distance from injecting borehole. It is caused by precipitation of particles which were eroded by grounwater flow during the suffosion of the solid skeleton near the borehole.

This research study aims to conduct the analysis and implementation of efficient algorithms for simulations of micro and nanoparticle transport models in porous media, coupled with the Darcy–Forchheimer fluid model, modified to include electromagnetic effects. The schemes developed were implemented via a parallel infrastructure for benchmark problems with a flexible algorithm that is efficient, robust, and stable. These improvements in the reliability and efficiency of simulations of nanoparticle transport in porous media contribute to the creation of an efficient method to counteract the contaminants in groundwater, and ultimately increase the availability of clean drinking water.
