Abstract
Wall-resolving large eddy simulations have been used in the last decades 
to study a wide class of
archetypal flow fields, useful to understand physical processes 
occurring in industrial and
environmental problems. Regarding environmental applications, turbulent 
flows characterized by
geometrical complexities, by the effect of rotation and stratification 
and by the presence of
dispersed phases have been successfully analyzed at a 
laboratory-experiment scale. Although such
studies have provided insights on fundamental physical processes, it is 
not straightforward to extend
such findings to full-scale applications. Recently, attempts have been 
directed toward the extension
of large eddy simulations to full scale, real-life environmental 
problems. These classes of
applications pose new modelling and numerical challenges. Scope of the 
seminar is to review wallresolving,
laboratory-scale LES of environmental interest carried out by the 
research group of Prof.
Armenio over the years as well as to show full-scale applications 
carried out with the model LESCOAST.
The latter has been recently developed by the same research group for 
the study of mixing
in coastal areas. Open issues on real-life LES of environmental 
applications will be also discussed.
