Finite-Element Modeling of Local Processes of Transfer in Porous Media

On the basis of a model of periodic structures and method of asymptotic expansions, a finite-element method is developed for solving problems of gas dynamics on the periodicity cell of a porous structure describing the distribution of gas motion velocities and pressure inside an individual pore. Peculiarities of local processes of transfer in pores with complex geometry are investigated as well as calculation errors of the finite-element method as applied to the problems considered.
