ENHANCEMENT OF ENVIRONMENTAL SECURITY BY MATHEMATICAL MODELLING AND SIMULATIONS OF PROCESSES

摘要

The objective of this article is to review benefits of mathematical modeling and simulations of different processes that are happening and which describe a system. A classification of different types of mathematical models is done as well as the steps in mathematical modeling. Depending on the system and the case study, an analytic mathematical model could be described by mass balance, energy, momentum and/or voltage equations, which are the building blocks in mathematical modeling of environmental systems. The mathematical models are used for steady state simulation, dynamic simulation, design, or process control. Packages for model development are identified. Computer implementation of the mathematical models for a few examples is presented. Numerical simulations aid in the prediction of future environmental concentrations of pollutants under various waste loading and/or management alternatives; in environmental impact assessment; to design, operate, and optimize the reactors; and, to offer pollution control alternatives, All of these uses contribute to the enhancement of environmental security.
