"Modeling the Transport of Nano-Sized Zero-Valent Iron in an Aquifer "

Nano-sized zero-valent iron (NZVI) is very potent in remediating a large range of soil contaminants. The nano-particles can move through an aquifer easily while having a high reactivity due to their large specific surface area. At the University of Stuttgart, an experiment was carried out to research the movement of NZVI through an aquifer in a radial flow field. To increase understanding of the underlying processes, a model had to be created that simulates the experiment. For the presented work, a model was created to simulate the transport of NZVI in a radial flow field using the advection-dispersion relation. The model was created using COMSOL Multiphysics.
