A multi-layer reactive transport model for fractured porous media

An accurate modeling of reactive flows in fractured porous media is a key ingredient to obtain reliable numerical simulations several industrial and environmental applications. For some values the physical parameters we can observe formation narrow region or layer around fractures where chemical reactions are focused. Here, transported solute may precipitate form salt, vice-versa. This phenomenon has been observed reported real outcrops. By changing its properties, this might substantially alter global flow response system thus actual transport solute: problem non-linear fully coupled. The aim work propose new mathematical model for media, by approximating both fracture these surrounding layers via reduced model. In particular, our main goal describe thickness evolution with model, compare it resolved equidimensional validation. As concerns approximation extend an operator splitting scheme time solve sequentially, at each step, process avoiding need monolithic solver, which be challenging due non-smoothness reaction rate. We consider bi- tridimensional test cases asses accuracy benefit proposed realistic scenarios.
