Abstract The current status of computer modeling of pollutant dispersion around a building is discussed. Presently, methods of Computation Fluid Dynamics (CFD) with a closure approach using equations for the turbulent kinetic energy and dissipation rate are believed to provide a practical solution for many applications. F3D kappa epsilon was used to compute the steady-state flow field around a building. Using this computed flow field, pollutant concentrations were computed using the C3D kappa epsilon model. Three versions of the C3D kappa epsilon model are evaluated by modifying the numerical approximations for the advection term using steady upwind, steady hybrid, and unsteady upwind procedures. The computed results are comparable with wind-tunnel measurements.
