Abstract

In urban neighborhood and around industrial plants, the atmospheric
dispersion of pollutants is strongly affected by the presence of
buildings. They affect the mean flow field and the turbulence and these
in turn will affect the concentrations levels. We describe the use of
Computational Fluid Dynamics models (adapted for the atmosphere),
following either an Eulerian/Eulerian approach or an hybrid
Eulerian/Lagrangian formulation. The results are illustrated using
measurements of the Mock Urban Setting Test (MUST) campaign performed in
the USA. Using the same field campaign, we will also show how we can use
data assimilation of the measurements between the buildings to improve
the numerical simulation in urban environments.
