Description (Dublin Core)

eng The transmission of dust particles is one of the interesting processes in the dispersion of aerosols. Due to the fact that it is
impossible to follow the track of every single particle, a lot of effects and their parameters must be known to simulate the
dispersion.
At the Harmo 7 conference a dynamic model to simulate the dispersion of odours was presented, before. This model is based on a
numerical solution of the Navier-Strokes equation. Building upon this effort the dispersion model was enhanced, so that it is now
possible to simulate the dispersion of aerosol particles. Extensive modifications were necessary to consider the aerodynamic and
physical characteristics of polydisperse aerosols. Effects as sedimentation, deposition, resuspension and agglomeration of aerosols are or will be integrated into the simulation model.
In order to realize a validation of such a complex dispersion model, our research group is developing two independent aerosol tracer
systems. Primary attention is paid to the environmental compatibility of the tracer dust. Both procedures are based on fluorescence
marked particles, but they differ from each other with regard to their methods of detection. This enables us to practice both
procedures at the same time. The dispersion model as well as the validation methods is objects of this paper.
