Simulation of the second moments of random field of concentration in a semispace with erlangian

Abstract

This work focuses on the mathematical modeling of admixture diffusion processes in a two-phase stratified semispace, taking into account the random disposition of sublayers and the condition of nonideal mass contact on interphases. The dispersion of the particle concentration field and the two-point correlation function of the field were determined for the diffusion process in the stratified semispace with an exponential distribution of inclusions. Additionally, software was developed for this model, and the influence of medium characteristics was investigated.
