Journal ArticleDOI
Validity of the local equilibrium assumption for modeling sorbing solute transport through homogeneous soils
TL;DR: In this article, a method is described whereby formulas for solute breakthrough curve time moments can be determined without knowledge of the nalytical solution to the mass transport model, and criteria for local equilibrium to be valid are derived by comparing the time moment formulas for the nonequilibrium and equilibrium models.
Journal ArticleDOI

TL;DR: An extensive overview on a number of extensions to the lattice Boltzmann method which allow to study multiphase and multicomponent flows on a pore scale level are given.
Journal ArticleDOI
Transport of ion‐exchanging solutes in groundwater: Chromatographic theory and field simulation
TL;DR: In this article, an analytical framework based upon the theory of chromatography is presented, which permits a priori characterization of certain key concentration profile features such as multiple fronts and plateau zones.
Journal ArticleDOI
Evaluation of the effects of porous media structure on mixing-controlled reactions using pore-scale modeling and micromodel experiments.
TL;DR: It is suggested that subcontinuum effects can play an important role in the overall extent of mixing and reaction in groundwater, and hence may need to be considered when evaluating reactive transport.
Journal ArticleDOI
Accuracy of operator splitting for advection‐dispersion‐reaction problems
TL;DR: In this article, the authors demonstrate that there is an inherent mass balance error present in the operator-splitting algorithm for problems involving continuous mass influx boundary conditions, and they also present a variant of the normal operator splitting algorithm in which the order of solving the advection-dispersion and reaction operators is reversed at each time step.
