N2 - Calculations of the dispersal of a nonbuoyant passive scalar emanating from an isolated chimney stack immersed in a turbulent boundary layer have been made. The numerical predictions were obtained by means of a Reynolds-averaged Navier-Stokes calculation method using a three-dimensional computation domain. The height of the stack was varied, and for one of the flows a building was present downstream of the source. Predictions of concentration distribution at ground level were compared with measurements obtained during scaled wind tunnel experiments. The results obtained by using the Reynolds-averaged Navier-Stokes calculation method were generally found to be in good agreement with the experimental values.
