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
