Method of numerical simulation for the air pollution dispersion

The paper can be included in the wide and complex thematic of the environment´s protection. The study case refers to a statistical mediation of spatial-temporal dispersion of pollutants in the air. The analogical model of this process is based on a partial derivatives equation of the second order, with respect to time (t) and with respect to a spatial variable in Cartesian space (s). The numerical simulation presented in detail in [1] operates with the “matrix of partial derivatives of the state vector”, denoted (Mpdx) to which Taylor Series are associated. It is interesting the systemic approach of this process of pollutants dispersion in the air, in two variants, respectively in isolated regime and in automatic control regime, for the limitation of pollutants at a certain concentration. A few results that have been obtained on the computer are presented and commented, underlining the advantages, restrictions and limits of the studied method.
