The workshop Environmental Dispersion Processes focused on mathematical models and simulation strategies that are required for predicting the dominant transport mechanisms in the natural environment. This aim was supported by extensive discussion of experimental and field studies. Examples of important environmental transport processes may be found by considering turbulent mixing of (stratified) gases and liquids, of ensembles of small particles or of heat. Such dispersion processes are essential in various situations such as sediment-transport in rivers and coastal areas, spreading of pollutants, dust and soot in urban environments or the heat- and mass-transfer across the ocean-surface, with direct connections to weather and climate predictions.
emphasis of the workshop was on a fundamental approach to this
multi-disciplinary field of research. This requires input and integration from
a variety of scientific and engineering disciplines. The many lively and
interesting discussions and presentations certainly contributed to realizing
this ambition. It helped to strengthen the Platform for Geophysical and
Environmental Fluid-mechanics (PGEF) in the
The workshop provided a platform for the exchange of knowledge and ideas in the field of multiscale modeling and simulation of large-scale problems in environmental fluid mechanics.
FOM and the COST-Action `LES-AID’ supported the workshop
financially. This allowed the
invitation of a number of international experts who provided detailed
presentations of their work. The chosen format of 1-hour presentations allowed
in addition ample time for open discussion. During the first week of EDP around
40 people participated, while the final two days attracted around 25 people.
Participants came from the
workshop had three focal areas:
· Fundamentals of turbulent dispersion
· Air quality monitoring and prediction
· Transport in rivers, coastal regions and ocean circulation
Next to theoretical and simulation studies, a number of presentations were devoted to experimental and field-studies to help keep a direct connection with environmental aspects. Ample attention was given to the effects of ensembles of particles that are embedded in a flow. Consequences of preferential clustering of inertial particles and inelastic particle-particle interactions were discussed at length.
