The experiments were performed in a street canyon and near uniform configuration with a building height to street width ratio of 1.5 under ambient winds perpendicular to the street. These flow conditions were studied as they are known to result in the largest street-level concentrations and hence ...
The aspect ratio, i.e. canyon-width to building-height ratio, ranges from 1 to 6. Gable roof buildings with 1:1 pitch are compared with flat roofed buildings. Velocity is measured using a particle-image-velocimetry technique with flow dynamics discussed in terms of mean flow and second- ...
This is performed using the CFD code FLUENTTM 6.3 for a street canyon of width to building height ratio W/H=1 with street-level line sources to model two-way traffic. A comparison between two steady-state RANS turbulence models, namely the standard k–ε and Reynolds Stress Model (RSM),...
This study investigates the impact of building aspect ratio (building-height-to-street-canyon-width-ratio), wind speed and surface and air-temperature difference (Δθs−a) on the heating environment within street canyon. The Reynolds-averaged Navier-Stokes (RANS) and energy transport equations ...
To enrich our understanding of the flow and pollu tant removal in urban areas, the wind and pollutant transport in idealized twodimensional (2D) street canyons of building-heightto-street-width (aspect) ratios (ARs) 0.0667, 0.090 9, and 0.25 were simulated by both the Reynolds-averaged Navier...
in addition to above-roof wind speed and direction, were measured over a period of three months. The street has a height-to-width (h/W) ratio of 0.6 and is of asymmetric horizontal alignment. The air flows in the area surrounding the building were modelled using a computational fluid flow...
