Simulation
results for traffic related fine particulate resuspension
in urban and
extra-urban streets
Dott. Abramo Agosti
ABSTRACT
After a brief introduction to the
problem of resuspension as a fundamental contribution
to traffic related fine particulate emissions in urban and extra-urban streets,
we show our CFD approach to the simulation of the problem, describing details
of applied turbulence models, dispersion models and numerical algorithms, and
show results on the estimation of resuspension
contribution in different traffic flow situations, depending on traffic
statistics, road geometry and asphalt characteristics.
