摘要：
Dispersion of automotive exhaust gas along urban roadways was studied through numerical simulation and wind tunnel experiments. Wind and concentration fields were calculated applying two and three dimensional finite difference models, using various roadway and surrounding configurations. Tracer gas dispersion experiments in a wind tunnel were implemented to validate the numerical simulations. For the various configurations, significant correlation was found between the numerical and experimental results. A case study on a real street canyon was also carried out.
