Abstract

A lattice gas model for the evaluation of transport and diffusion parameters of stack emissions in air R. Cipollone & A. Sciarretta Dipartimento di Energetica, Universita dell'Aquila, Italy Abstract A quantitative Lattice Gas model is proposed in this paper for the prediction of the interaction between pollutant emissions from power plant stacks and the surrounding environment. The model takes into account turbulent diffusion, wind transport, soil deposition, plume rise and transient effects, also the presence of irregular spatial domains. These features cannot be achieved by current engineering models that derive from the Gaussian plume equation, without some semi-empirical relationship to evaluate diffusion coefficients and plume rise height. In spite of the complexity of the processes described, the implementation of the model requires little programming effort and the simulations are not affected by instability. These aspects, together with the fact that no parameter
