The effect of fluid density variations on mixed convective (advective and density‐driven) transport in fractured rock is examined. Assuming a representative natural hydraulic gradient in a vertical fracture, breakthrough curves for variable‐density systems are shown to be significantly different from those with constant‐density conditions for even very small solute source concentrations (as low as approximately 2.3 g L−1 total dissolved solids, corresponding to 6.4% of seawater salinity). We… 

Numerical stability analysis of two‐dimensional solute transport along a discrete fracture in a porous rock matrix

This work reports numerical stability conditions in two‐dimensional solute transport simulations including discrete fractures surrounded by an impermeable rock matrix. We use an advective‐dispersive

Modeling Flow and Solute Transport in Fractured Porous Media at Jinping I-Hydropower Station, China

AbstractA model that couples the rock matrix and fracture flow is employed to simulate the flow and solute transport in fractured porous media. The porous matrix is represented using an equivalent

Heat Tracing in a Fractured Aquifer with Injection of Hot and Cold Water

The feasibility and utility of cold water tracer tests in hot fractured aquifers to boost and characterize the thermal matrix diffusion from the matrix towards the flowing groundwater in the fractures is shown.

Influence of the grain structure on solute transport in constructed inhomogeneous media from pore-scale simulations

Grain structures widely exist in porous media and play a significant role in solute transport in media. One homogeneous and three inhomogeneous grain structures were constructed, and the finite

A breakthrough curve analysis of unstable density‐driven flow and transport in homogeneous porous media

In certain hydrogeological situations, density variations occur because of changes in solute concentration, temperature, and pressure of the fluid. These include seawater intrusion, high‐level

Contaminant Transport in Nonisothermal Fractured Porous Media

Alternative formulations of the analytical modeling for contaminant transport in nonisothermal fractured porous media are presented. Transient and steady heat flows are coupled with solute transport,

Contaminant transport in fractured porous media: Analytical solutions for a system of parallel fractures

An exact analytical solution is developed for the problem of transient contaminant transport in discrete parallel fractures situated in a porous rock matrix. The solution takes into account advective
