Fractional reaction-diffusion equation [PDF]

open access: yesThe Journal of Chemical Physics, 2003
A fractional reaction-diffusion equation is derived from a continuous time random walk model when the transport is dispersive. The exit from the encounter distance, which is described by the algebraic waiting time distribution of jump motion, interferes with the reaction at the encounter distance. Therefore, the reaction term has a memory effect.

Unified Fractional Kinetic Equation and a Fractional Diffusion Equation [PDF]

open access: yesAstrophysics and Space Science, 2004
In earlier papers Saxena et al. (2002, 2003) derived the solutions of a number of fractional kinetic equations in terms of generalized Mittag-Leffler functions which extended the work of Haubold and Mathai (2000). The object of the present paper is to investigate the solution of a unified form of fractional kinetic equation in which the free term ...

Compact difference scheme for distributed-order time-fractional diffusion-wave equation on bounded domains [PDF]

open access: yes, 2015
In this paper, we derive and analyse a compact difference scheme for a distributed-order time-fractional diffusion-wave equation. This equation is approximated by a multi-term fractional diffusion-wave equation, which is then solved by a compact ...

Numerical simulation for the three-dimension fractional sub-diffusion equation [PDF]

open access: yes, 2014
Fractional sub-diffusion equations have been widely used to model sub-diffusive systems. Most algorithms are designed for one-dimensional problems due to the memory effect in fractional derivative.

Fractional calculus of periodic distributions [PDF]

open access: yes, 2011
Two approaches for defining fractional derivatives of periodic distributions are presented. The first is a distributional version of the Weyl fractional derivative in which a derivative of arbitrary order of a periodic distribution is defined via Fourier

Modelling solute transport in soil columns using advective-dispersive equations with fractional spatial derivatives [PDF]

open access: yes, 2010
Solute transport in soils is commonly simulated with the advective–dispersive equation, or ADE. It has been reported that this model cannot take into account several important features of solute movement through soil.
