Abstract
In the framework of developing a new remote sensing instrument for
identification of gross polluting vehicles, the CFD modelling approach has been
applied to study the effects of parameters affecting the exhaust gas plume
characteristics of one and two moving vehicles in a two lane street canyon of
width/height ratio equal to 1 with D5 ambient flow normal to the canyon.
The calculations have been performed using the ADREA-HF code in a
moving coordinate system, with cars and site geometry fully resolved. Single car
calculations were performed with the main parameter the car speed and a
qualitative comparison is made against existing experimental field
