AbstractAs the computation of turbulent flow around a building has almost reached the point of routine calculation on a medium size computer, it is time to look at the next step of computation of contaminant dispersion around a building. The diffusion equation approach is a logical extension of the two equation model used for turbulent flow around a building. This approach still awaits a better model of turbulent diffusion of scalars. The alternative stochastic models, especially the large eddy simulation, have met with some success. Unfortunately, for the latter method, spectral information of the turbulence of the approach flow and a powerful computer are prerequisites.
