COMPUTER MODELING OF MUTUALLY BOUNDED FILTRATION AND SUFFUSION PROCESSES IN HETEROGENEOUS POROUS ENVIRONMENTS

The article is numerically investigated mathematical model of filtration in the soil under the influence of chemical and mechanical phenomena suffusion. The numerical solution of nonlinear boundary value problem corresponding finite element method in twodimensional case is offered. Software implementation of existing FEM algorithms implemented in the environment FreeFem++. Using software established series of numerical experiments and analysis, the main results of which are shown in the graphs. It is shown that the results of numerical experiments in the study of filtration and suffusion of soil processes are different if to consider and do not consider the impact of heat and salt transferring and suffusion phenomena. For example, the relative amplitude of difference in the filtration pressures of about 17%. The areas for further work – is quality researches of relevant nonlinear boundary problems and their approximate solutions.
