Mathematical and Computer Modeling Admixture Spread by Two Ways in a Medium with a Random Sublayer

Abstract

The mathematical model of heterodifussion of the admixture in a two-phases body with randomly located layer taking into account sorption-desorption processes are proposed. Calculating formulas for the modeling the admixture spread are obtained. Based on the formulas computer modeling heterodifussion process is used for the estimating an influence of physical characteristics of the body on the distributing concentration fields of the admixture.
