The urban boundary layer (UBL) is the part of the atmosphere in which most of the planet's
population now lives, and is one of the most complex and least understood microclimates …

Cities are facing significant challenges due to low outdoor air quality. Hence, a growing
number of studies have been conducted to develop strategies for improving air quality. This …

The wind velocity and surface pressure of the model of a group of urban blocks made of low-
rise buildings with a high-rise building in the center were measured using a wind tunnel. Not …

Air pollution and heat stress are major concerns associated with the liveability, resilience
and sustainability of cities. They directly affect health and comfort and are associated with …

Studies are still required to understand how rural/marine wind remove ground-level
pollutants released uniformly in street networks of high-rise urban areas. The link between …

We designed and exclusively performed a wind tunnel experiment to obtain high-quality and
high-resolution measurement results for three components of mean and fluctuating …

The goal of this paper is to discuss the spatial averaging concept in environmental
hydraulics and develop it further by considering transport equations for fluid momentum …

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 …

Direct numerical simulations (DNS) are conducted for turbulent flow through pipes with three-
dimensional sinusoidal roughnesses explicitly represented by body-conforming grids. The …

Large eddy simulation (LES) of the airflows around various types of block arrays was
performed to estimate the pedestrian wind environment. Five types of uniform staggered …
