Application of Flux Corrected Transport for Multicomponent Reactive Transport Modeling
Reactive transport describes the coupling among flow, transport and chemical reactions occurring in porous media; and therefore it is important in areas such as aquifer remediation, groundwater contamination, geochemical reaction modeling and CO2 sequestration. Due to the large time scales involved and/or the lack of accessibility to the subsurface, in most of these studies an adequate represen...
متن کاملAssessment of parametric uncertainty for groundwater reactive transport modeling
The validity of using Gaussian assumptions for model residuals in uncertainty quantification of a groundwater reactive transport model was evaluated in this study. Least squares regression methods explicitly assume Gaussian residuals, and the assumption leads to Gaussian likelihood functions, model parameters, and model predictions. While the Bayesian methods do not explicitly require the Gauss...
متن کاملA three-dimensional analytical tool for modeling reactive transport.
In this note, we present a public domain analytical reactive transport modeling tool (ART3D, version 2.0). The tool is developed in FORTRAN and can be used for solving a system of a set of partial differential equations coupled with a first-order reaction network. ART3D uses a novel analytic solution technique proposed by Clement. The new software includes options for performing Monte Carlo sim...
متن کاملReactive Transport Modeling of Phosphate Mineral Dissolution in High-p
Introduction: Phosphate is among the nutrients considered critical for all known life [1-4]. The ion is a component in ATP, DNA, RNA, phospholipid cell membranes and required in numerous fundamental biochemical reactions [5]. Phosphorus, either as phosphate or a more reduced species such as phosphite, is also considered crucial in pre-biotic reactions that may have led to the origin of life on ...
متن کاملExtraction of model parameters for reactive solute transport
In the present study, tried to examine the reactive solute relationships for transport and degradation processes through the rockfill media. By applying the analytical solution of reactive transport, the 1st to 3rd theoretical temporal moments have been extracted then, by using two methods of curve fitting and temporal moment matching, the coefficients of dispersion and degradation have been ex...
