FAST RESPONSE MODELING OF A TWO BUILDING URBAN STREET CANYON

摘要

QWIC-URB was compared to the twin high-rise building data of Ohba et al. (1993). The results qualitatively predict the flow field well for simple canyon flow, however, significant quantitative differences were found. For larger Fig. 3: Particle traces showing the upstream and canyon vortices (freestream wind is from right to left normal to the obstacles). W/H, the mass conservation method produces physically significant wall normal canyon vortices that may be important in the transport of pollutants out of the canyon.
