Modeling and Analysis of Concentration Fields of Nonlinear Competitive Two-Component Diffusion in Medium of Nanoporous Particles

摘要

We proposed nonlinear mathematical model of two-component competitive diffusion in bounded nanoporous media of spherical particles. Exact analytical solutions of this model were constructed with application of the Heaviside operational calculus and the Cauchy fundamental matrixes. We conduct numerical modeling and analysis of dynamics of variation of concentration in particle for interparticle space in zeoilite for the process of competitive two-phase diffusion.
