摘要: Abstract The flow characteristics inside urban street canyons were studied in a laboratory water channel. approaching direction was horizontal and perpendicular to the axis. width adjusted form of aspect ratios 0.5, 1.0, 2.0. velocity field turbulent intensity measured with laser Doppler anemometer at various locations within canyons, which used elucidate pattern canyons. It found that previous numerical modeling results are good agreement current experimental most locations. For canyon ratio belongs wake interference regime, mean fluctuating components more difficult measure as compared other two cases because its complicated pattern. Some guidelines for developed based on measurement results. data presented this paper can also be as...
