The article considers the problem of constructing self-similar solutions of a system of nonlinear differential equations modeling mutual diffusion processes in multicomponent media. An analysis of a mathematical model taking into account complex interactions of components and the nonlinear nature of transfer processes is carried out. Approximate solutions of the system are found, allowing one to describe the behavior of concentration profiles in various modes. Asymptotic representations of solutions for regular, unlimited and limited cases are obtained, and the behavior of a two-sided linear stationary equation arising at intermediate stages of analysis is studied. The results are of interest for diffusion theory and applied problems of mathematical modeling of complex physical processes.
