CrunchFlow
An open-source software package for simulating reactive flow and transport applied to a variety of problems in the Earth and environmental sciences that can include an arbitrary number of reactions, including mineral dissolution/precipitation, ion exchange, surface complexation, and microbially mediated reactions (Steefel et al, 2015). The code is based on a finite volume discretization of the governing coupled partial differential equations that link flow, solute transport, and multi-component equilibrium and kinetic reactions in porous and/or fluid media. Two approaches are available at runtime for coupling reactions and transport: (1) a global-implicit approach that solves transport and reactions simultaneously, and (2) an operator-splitting approach based on a sequential non-iterative solve. CrunchFlow/CrunchTope is the recipient of an R&D 100 Award for Cutting-Edge Technologies in 2017.
