This report describes the fracture-scale mechanisms acting on solute transport in fractured
aquifers under natural-flow conditions. It focuses on low-permeability rocks where advection …

Dispersion of solutes in a variable aperture fracture results from a combination of molecular
diffusion and velocity variations in both the plane of the fracture (macrodispersion) and …

Laboratory experiments have been carried out to study groundwater flow in a single fracture
under the conditions of different surface roughness and apertures. We found that the …

We have experimentally studied solute transport in a single fracture (SF) under non-Darcian
flow condition which was found to closely follow the Forchheimer equation at Reynolds …

The purpose of this work is to model dispersion at the macroscale as the result of
mechanisms acting at the microscale. We simulated advection and molecular diffusion of a …

An expression is analytically presented for the shear dispersion, or Taylor and Aris
dispersion, of a solute transporting in a coupled system, which consists of a matrix and a …

In fractured porous media, interactions between immiscible fluid phases within the fractures
place a critical control on system behavior. A key component of the interactions is the …

A mobile-immobile model (MIM) of reactive solute transport for an injection well was
investigated in a radial two-zone confined aquifer system made up of the aquifer formation …

The relationship between the longitudinal dispersion (DL) and Peclet number (Pe) is crucial
for predicting and simulating tracer through the variable‐aperture fracture. In this study, the …

The study of transport processes in a single fracture is the basis of understanding transport
in complex fractured networks. Many single fractures in the field are filled with sediments …
