摘要：

A numerical model which simulates the dispersion of passive scalars within an urban canyon is proposed and some initial verification of the model undertaken. It is then used to investigate three-dimensional characteristics of the concentration field established for flow perpendicular to canyons with emissions released near the floor of the canyon by motor vehicles. In particular, the influence of canyon geometry on the concentration field is studied and some general observations made concerning the location of maximum concentrations.
