This article deals with the state-of-the-art of experimental and numerical studies carried out
regarding air pollutant dispersion in urban environments. Since the simulation of the …

Air pollutants emitted from vehicles in street canyons may be reactive, undergoing mixing
and chemical processing before escaping into the overlying atmosphere. The deterioration …

In this paper, we describe the PALM model system 6.0. PALM (formerly an abbreviation for
Parallelized Large-eddy Simulation Model and now an independent name) is a Fortran …

Over the last 50 years the large-eddy simulation (LES) technique has developed into one of
the most prominent numerical tools used to study transport processes in the atmospheric …

Improper natural ventilation practices may deteriorate indoor air quality when in close
proximity to roadways, although the intention is often to reduce energy consumption. In this …

A significant amount of the fuel consumed by marine vehicles is expended to overcome skin-
friction drag resulting from turbulent boundary layer flows. Hence, a substantial reduction in …

Using a numerical weather forecasting code to provide the dynamic large-scale inlet
boundary conditions for the computation of small-scale urban canopy flows requires a …

Outdoor urban ventilation in a real complex urban area is investigated by introducing a new
ventilation indicator–the “air delay”. Computational Fluid Dynamics (CFD) simulations are …

In the last two decades substantial advances have been made in the understanding of the
scientific basis of urban climates. These are reviewed here with attention to sustainability of …

Single-point measurements from towers in cities cannot properly quantify the impact of all
terms in the turbulent kinetic energy (TKE) budget and are often not representative of …
