EVALUATION OF NATURAL AND TRAFFIC-PRODUCING TURBULENCES USING FULL SCALE DATA FROM FOUR STREET CANYONS
Description (Dublin Core)
eng
In urban areas, high air pollutant concentrations may be observed, mostly within street canyons, where buildings and
other obstacles disturb the airflow and turbulence. Air motions inside the street canyons are influenced by aerodynamic and thermal
effects and by the movements of the vehicles. Parameters related with natural and traffic produced turbulences are estimated for four
street canyons considering all wind directions. Available data used include air pollution concentrations measured in Göttinger
Strasse (Hannover, Germany), Schildhornstrasse (Berlin, Germany), Jagtvej (Copenhagen, Denmark) and Hornsgatan (Stockholm,
Sweden), and background pollution, wind speed and direction measured on the roof of a nearby building and information of traffic
flow. For each street canyon, the variation with traffic density of critical wind speed (that equals the contributions of turbulent
motions related to wind and traffic to the effective velocity variance inside the street canyon) is also studied.
