Simulation of Reactive Transport in Fractured Porous Media

Abstract Numerical simulations of reactive transport in fractured porous media require the solution coupled physical and chemical processes that depend on fractures. Such are described by a system nonlinear partial differential-algebraic equations, while strong heterogeneities characterise This paper presents an approach to simulate single-phase flow non-isothermal with mineral dissolution precipitation media. Our numerical strategy is based two ingredients. First, model equations consist differential for fluid flow, heat transfer solute algebraic representing reactions. Second, fractures explicitly represented treated as lower-dimensional objects. The discretised using finite-volume methods, at each time step, we solve Newton’s method. With simulations, illustrate our model’s ability accurately describe two-way interaction between multi-physical two- three-dimensional intersecting
