Abstract

Pollutant transport is a problem of paramount importance when dealing with environmental protection. In transport problems we have generally interaction of different fields, e.g. mechanical, thermal, hydraulic, chemical, electric, hence the most general way to analyse such a problem, is multi-component mechanics. Mixture theories and averaging approach represent valuable theoretical tools to obtain the governing equations. The resulting mathematical model usually involves several non-linear Partial Differential Equations, defined in very large domains, both in space and time and solutions are possible only using numerical methods. The applicability and efficiency of the numerical model basically depend on the adopted solution strategy, which has to be carefully analysed. The paper shortly presents the governing equations, then introduces some numerical techniques to solve the problem and discusses the respective properties.
