The present course offers a wide overview of the
state-of-the-art, with applications ranging from
microclimate, wind engineering, to mesoscale, meteorology,
and their coupling. Reynolds Averaging (RANS) and Large-Eddy
(LES) approaches are discussed and their respective
capabilities at meso- and microscales are evaluated, with
focus on realistic inflow, wall modelling, Uncertainty
Quantification and validation.

Description:
There is an increasing interest for the
application of Computational Fluid Dynamics (CFD) to the
study of flows in the lower part of the atmospheric boundary
layer (ABL). The simulation of atmospheric flows, often over
complex domain, is necessary for the estimation of wind
loads on buildings, wind turbine siting, pollutant
dispersion and pedestrian wind comfort.
The present course offers a wide overview
of the state-of-the-art, with applications ranging from
microclimate, wind engineering, to mesoscale, meteorology,
and their coupling. Reynolds Averaging (RANS) and Large-Eddy
(LES) approaches are discussed and their respective
capabilities at meso- and microscales are evaluated, with
focus on realistic inflow, wall modelling, Uncertainty
Quantification and validation. The discussion is completed
by the presentation of examples of practical implementation
for Open Source Codes such as WRF and OpenFOAM as well as
in-house and commercial CFD software.
The lecture series director is Prof. Jeroen van Beeck
from the von Karman Institute.
