Sentence examples for matrix diffusion and from inspiring English sources
Matrix diffusion and sorption are important processes controlling radionuclide transport in crystalline rocks.
The principal differences between the models are mesh size, network connectivity, matrix diffusion and anisotropy.
Consequently, there should be little effect of sorption, matrix diffusion, and hydrodynamic dispersion in the unsaturated zone on the concentrations of CFCs in groundwater (IAEA 2006).
Peat effectively attenuated the conservative solute through matrix diffusion, and heterogeneity in peat properties influenced the effectiveness of this retardation.
The field scale simulations indicated that matrix diffusion and fracture filtration can significantly reduce colloid migration distance.
An innovative particle-tracking method was used to simulate transport that includes the processes of advection, dispersion, matrix diffusion, and sorption.
In fractured bedrock aquifers, reduction of Cr VI) in the rock matrix can enhance attenuation beyond that from matrix diffusion only, and potentially reduce back diffusion if concentrations in fractures decline following source reduction via natural processes or engineered remediation.
Finally, numerical results of various temporal moments have been predicted to study the behavior of reactive solute in the fracture, and it was found that the behavior of solute mass recovers, mean arrival time and second time moment are nonlinear along the travel distance for solute in the fracture in the presence of matrix-diffusion and decay rate coefficient.
As a result, the effects of Fickian dispersion and matrix diffusion on solute transport are decoupled, and thus the resulting breakthrough curve can be analyzed in terms of those two functions.
In a first step, constant fracture aperture, it is shown that matrix diffusion is multidimensional and that stagnant water is a major pathway for the diffusive mass transfer into the rock matrix.
The model accounts for matrix diffusion, equilibrium sorption and non-linear relative transmissivity effects that influence groundwater flow within fractures as the DNAPL disappears.
