Abstract Large Eddy Simulation (LES) undeniably has the potential to provide more accurate
and more reliable results than simulations based on the Reynolds-averaged Navier-Stokes …

Near-field pollutant dispersion in the urban environment involves the interaction of a plume
and the flow field perturbed by building obstacles. In the past two decades, micro-scale …

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 …

The global trend towards urbanisation explains the growing interest in the study of the
modification of the urban climate due to the heat island effect and global warming, and its …

Turbulence modeling and validation by experiments are key issues in the simulation of
micro-scale atmospheric dispersion. This study evaluates the performance of two different …

Given the complexity of urban wind flow, acceptable wind conditions can hardly be achieved
in all regions within an urban area. In some regions, high wind speeds can lead to wind …

The dispersion of pollutants exhausted from a building roof stack located in a tower was
investigated using various types of k–ε turbulence models, ie, a standard k–ε model, a RNG …

Tall buildings in urban environments can negatively affect drone navigation, by creating
turbulence and local regions of high-velocity winds. This jeopardizes the safety of the public …

Courtyards, a historical architectural feature surrounded by buildings, are common in urban
housing and residential complexes. These spaces, often open-air and with rooms facing …

This study aims to investigate the mixing and displacement ventilation systems commonly
used in buildings indoor ventilation by means of computational fluid mechanics (CFD). The …
