ABSTRACT

This paper describes the mathematical modeling and associated computer simulations of environmental problems related to flow and heat/mass transfer. Many key “issues” in designing environmental protection systems, and in performing environmental risk assessment and control, are related to the behavior of fluids in turbulent flow, often involving more than one phase, with chemical reaction or heat transfer. Computational-Fluid-Dynamics (CFD) techniques have shown great potential for analyzing these processes and are very valuable to the environmental engineer and scientist, by reducing the need to resort to “cut and try” approaches to the design of complex environmental-protection systems and to any relevant decision-making process. Multi-dimensional, multiphase dynamic models for the dispersion of air, water and soil pollutants and for the prediction of environmental risks are presented. Results using model simulations are presented for some cases of atmospheric and marine pollution, as well as for the environmental risks of fires and of petrol-tank explosions. It is concluded that the results are physically plausible and can be used with confidence. Air, water and soil management systems can be improved by the application of these computational prediction techniques.
