Brownian Simulation of Matrix Diffusion

MRS Proceedings, 2000
ABSTRACTThe commonly used approach in dealing with matrix diffusion is to assign an effective diffusion constant for the radionuclide in the rock matrix. The idea behind this approach is that, on a scale much larger than the pore size, the irregularities tend to cancel out.

Brownian Motion and Diffusion

1989
Let us pause in this chapter for a little intermezzo with a discussion of the generalized diffusion equation (36.18). We express the momentum density g in terms of the particle current density j as g(x,t) = mj(x,t).

Brownian Motion and Diffusion Processes

1996
This Lesson is mainly devoted to the study of continuous time processes defined by differential equations. The crucial mathematical tool is the stochastic integral.

Brownian diffusion in nonequilibrium gas

Journal of Engineering Physics, 1974
The Brownian motion in a nonequilibrium gas is considered within the framework of the stochastic transfer theory in linear Boltzmann systems. The equation for Brownian diffusion of particles is derived in inhomogeneous flows of rarefied gas.

Diffusion of interacting Brownian particles

Journal of Physics A: Mathematical and General, 1978
The author develops a theory of Brownian motion for interacting spherical particles suspended in a fluid. Due to potential and hydrodynamic interactions the effective diffusion coefficient depends on the concentration of particles. The correction to the bare diffusion coefficient is derived to first order in the concentration.

Osmosis, Diffusion and Brownian Motion

1969
In 1748 Nollet showed that if an animal bladder was used to separate water and alcohol, water passed through the bladder into the alcohol but no alcohol passed through the bladder into the water. The bladder is said to possess a property of selective transmission and it may be considered to consist of a mesh of such a size that small particles such as ...
