Title

Joint Urban 2003 Street Canyon Experiment

Abstract

The prior field and laboratory experiments on street canyon flow were reviewed to evaluate the next generation of urban dispersion models. Much information of dispersion and flow patterns in the urban street canyon was obtained from reduced-scale wind-tunnel experiments. Several studies show that a helical vortex is formed between two buildings if the wind is within 60 degrees of perpendicular to the building face, otherwise no vortex forms. The measurement of wind velocities at a few positions in a street canyon between two farm house buildings with peaked roofs shows that the canyon vortex is highly intermittent and the mean filed is dominated by turbulent fluctuations.
