Reactive Multiphase Flow in Porous Media at the Darcy Scale: a Benchmark proposal

Description and data files for a "Reactive Two-phase flow Benchmark" Modeling reactive multiphase multicomponent flow in porous media leads to a highly nonlinear coupled system of degenerate partial differential equations and algebraic and/or ordinary differential equations, requiring special numerical treatment. The Benchmark consists of five test problems in total (both in 1D and in 2D), with varying degrees of difficulty, designed to verify the algorithms and the codes dedicated to simulate coupled isothermal Hydro-Chemical processes during injection and storage of CO2 in the subsurface. It is intended to be used as a basis for comparing codes in order to better understand different couplings such as chemical reactions with two-phase flow, phase behavior with equilibrium reactions, dissolution and precipitatio
