Abstract
The basic similarity requirements for the wind-tunnel simulation of building-effects on pollutant dispersion were obtained by the non-dimensional analysis of the system of equations of flow and pollutant dispersion. The availabilities of using regular passive turbulence simulation and instruments techniques for building-effects wind-tunnel experiments were studied by a practical wind-tunnel campaign. It was concluded that the incomplete simulation of atmospheric boundary layer and slow instrument responses exist in most of wind tunnels possibly due to the limitations of simulation devices and instrument conditions, however, it is possible, by simulating the key turbulence characteristics in oncoming flow and improving the sampling procedure, to give a reasonably simulation for the effects of buildings on pollutant dispersion in a wind tunnel.
