Journal ArticleDOI
Reactive transport codes for subsurface environmental simulation
Carl I. Steefel,C. A. J. Appelo,Bhavna Arora,Diederik Jacques,Thomas Kalbacher,Olaf Kolditz,Vincent Lagneau,Peter C. Lichtner,K. U. Mayer,Johannes C. L. Meeussen,Sergi Molins,David Moulton,Haibing Shao,Jirka Šimůnek,Nicolas Spycher,Steven B. Yabusaki,Gour Tsyh Yeh +16 more
TL;DR: A general description of the mathematical and numerical formulations used in modern numerical reactive transport codes relevant for subsurface environmental simulations is presented, along with a selective list of applications that highlight their capabilities and historical development.
Journal ArticleDOI
An investigation of the effect of pore scale flow on average geochemical reaction rates using direct numerical simulation
TL;DR: Molins et al. as mentioned in this paper investigated the effect of pore scale flow on average geochemical reaction rates using direct numerical simulation and found that the effect depends on the pore size.
Journal ArticleDOI
Pore-scale controls on calcite dissolution rates from flow-through laboratory and numerical experiments.

TL;DR: The difference between pore- and continuum-scale results due to transport controls was discernible with the highly accurate methods employed and is expected to be more significant where heterogeneity is greater, as in natural subsurface materials.
Journal ArticleDOI
Coupling between geochemical reactions and multicomponent gas and solute transport in unsaturated media: A reactive transport modeling study
Sergi Molins,K. U. Mayer +1 more
TL;DR: In this paper, gas attenuation in partially saturated landfill soil covers, methane production, and oxidation in aquifers contaminated by organic compounds (e.g., an oil spill site) and pyrite oxidation in mine tailings are investigated.
Journal ArticleDOI
Vadose zone attenuation of organic compounds at a crude oil spill site - interactions between biogeochemical reactions and multicomponent gas transport.
TL;DR: Simulation results confirm that the main degradation pathway can be attributed to methanogenic degradation of organic compounds in the smear zone and the vadose zone resulting in a contaminant plume dominated by high CH(4) concentrations and highlight the need to better delineate gas fluxes at the model boundaries, which will help constrain contaminant degradation rates, and ultimately source zone longevity.
