A Numerical Study on Pedestrian-Level Wind Environment in Different Types of Residential Area Streets in Tianjin

The spatial morphology of street significantly affects urban pedestrian-level wind environment and further has a great influence on human outdoor thermal comfort. Previous studies usually simplify urban streets as 2D or 3D street canyons with consecutive street interface, which is obvious different from the spatial morphology of Chinese residential area streets. This may cause wind environment difference between them. Taking Tianjin as the research area, this study firstly classified local residential areas into several categories based on its spatial morphological characters. Numerical simulation was then conducted to analyze the pedestrian-level wind environment between each category of street. Key spatial morphological factors that affect pedestrian-level wind were found. Meanwhile, this study figured out the pedestrian-level wind environment difference between Tianjin’s actual urban streets and simplified street canyons. Aspect ratio, which is the common morphological indicator used in street ventilation studies, was proved to be unapplicable in ventilation studies for Chinese residential area streets. This chapter suggests several optimization methods according to local climate condition, and provides theoretical references for residential area planning and design for Tianjin and other Chinese cities with comparable climate conditions.
