New stochastic model for dispersion in heterogeneous porous media: 1. Application to unbounded domains
A new model of solute dispersion in porous media that avoids Fickian assumptions and that can be applied to variable drift velocities as in non-homogenous or geometrically constricted aquifers, is presented. A key feature ...
Closed form solution of an exponential kernel integral equation
(Scientific Journals International, 2007)
In this note a Fredholm integral equation of the first kind with exponential expressions for the kernel and right hand side is considered. The task of finding a practically usable solution to such an equation may need ...
Iterative solution of quadratic tensor equations for mutual polarisation
(Hindawi Publishing, 2002)
To describe mutual polarisation in bulk materials containing high polarisability molecules, local fields beyond the linear approximation needs to be included. A second order tensor equation is formulated that describes ...
