Diffusion in spatially and temporarily inhomogeneous media.
In this paper we consider diffusion of a passive substance C in a temporarily and spatially inhomogeneous two-dimensional medium. As a realization for the latter we choose a phase-separating medium consisting of two substances A and B , whose dynamics is determined by the Cahn-Hilliard equation. Assuming different diffusion coefficients of C in A and B , we find that the variance of the distrib...
متن کاملDiffusion in spatially and temporarily inhomogeneous media: Effects of turbulent mixing
We consider diffusion of a passive substance C in a phase-separating nonmiscible binary alloy under turbulent mixing. The substance is assumed to have different diffusion coefficients in the pure phases A and B , leading to a spatially and temporarily dependent diffusion ‘‘coefficient’’ in the diffusion equation plus convective term. In this paper we consider especially the effects of a turbule...
متن کاملBranching diffusion in inhomogeneous media
We investigate the long-time evolution of branching diffusion processes (starting with a finite number of particles) in inhomogeneous media. The qualitative behavior of the processes depends on the intensity of the branching. In the super-critical regime, we describe the asymptotics of the number of particles in a given domain. In the sub-critical and critical regimes, we describe the distribut...
متن کاملHeat diffusion in inhomogeneous media Steady state conduction
The system under examination consists of a mix of N discrete particles embedded in an otherwise continuous matrix. We will assume that the particles are spheres. The spheres each have a radius Ri, thermal conductivity κi, and position ri = (xi, yi, zi) relative to a common origin, for i = 1, 2, . . . , N . Assume that the radii are dimensionless (scaled with an appropriate length, e.g., the ave...
متن کاملSpeed of reaction-diffusion fronts in spatially heterogeneous media.
The front speed problem for nonuniform reaction rate and diffusion coefficient is studied by using singular perturbation analysis, the geometric approach of Hamilton-Jacobi dynamics, and the local speed approach. Exact and perturbed expressions for the front speed are obtained in the limit of large times. For linear and fractal heterogeneities, the analytic results have been compared with numer...
