Query: Reactive flow in fractured porous media   In this work we present a model reduction procedure to derive a
hybrid-dimensional framework for the mathematical modeling of reactive
transport in fractured porous media. Fractures are essential pathways in the
underground which allow fast circulation of the fluids present in the rock
matrix, often characterized by low permeability. However, due to infilling
processes fractures may change their hydraulic properties and become barriers
for the flow creating impervious blocks. The geometrical as well as the
physical properties of the fractures require a special treatment to allow the
subsequent numerical discretization to be affordable and accurate. The aim of
this work is to introduce a simple yet complete mathematical model to account
for such diagenetic effects where chemical reactions will occlude or empty
portions of the porous media and, in particular, fractures.
