The MOOSE geochemistry module (original) (raw)

2021

Abstract

The MOOSE geochemistry module can solve models involving aqueous geochemistry, including aqueous equilibrium, kinetics, oxidation-reduction, sorption and surface complexation, dissolution-precipitation and gas buffering. One aspect that makes the geochemistry module different to other codes is the ease of coupling additional physics to the geochemical functionality. In particular, when used in conjuction with the MOOSE PorousFlow module, sophisticated reactive-transport simulations may be performed, including multi-phase and unsaturated fluid flows, high-precision equations of state for fluids, dynamic porosity and permeability distributions, and sophisticated numerical stabilization. Geomechanics may also be incorporated by using MOOSE's TensorMechanics module, to explore the interplay between geomechanical stresses and strains, and fluids, heat and reactions. Geochemical models are used to understand the chemistry of natural waters and other aqueous solutions and their interac...
