multicomponent diffusion, implicit finite-difference scheme, concentration profiles, non-ideal contactAbstract
Diffusion plays an important role in creating of new composite materials because it and accompanying phenomena participate in the formation of so-called transition layers. This paper presents possible boundary conditions for diffusion problems involving non--ideal contact between materials. A discontinuity in concentrations is also possible in the presence of ideal contact, due to differences in the mobilities of elements in different materials. Non-ideal contact leads to singularities in the boundary conditions, which may be due to various physical causes and leads to the concept of diffusion resistance at the boundary. It is shown that, within the framework of thermodynamics, the condition with an exponential dependence of the discontinuity in concentrations on temperature is substantiated. An algorithm for numerically solving the conjugate diffusive problem was developed based on component-wise separation of equations and an implicit second--order difference scheme, which is analogous to separation by physical processes. The boundary conditions were also approximated to second order using a Taylor series representation of the unknown quantities over small spatial steps (different for different regions) in the vicinity of the boundary. Using the problem of concentration redistribution between two materials as an example, the convergence of the algorithm and the consistency of the resulting concentration distributions at different points in time are illustrated. The parameters chosen for illustrations comply with thermodynamic constraints. Diffusion resistance at the interface between materials affects the concentration distribution and the rate at which equilibrium is established. Cross-diffusion coefficients do not alter the qualitative influence of imperfect contact on concentration redistribution. Such problems and the proposed algorithm can be useful in modeling the synthesis of composite materials, as well as in problems involving welding, soldering, and coating.
