Journal ArticleDOI
City breathability in medium density urban-like geometries evaluated through the pollutant transport rate and the net escape velocity
Jian Hang,Qun Wang,Xieyuan Chen,Mats Sandberg,Wei Zhu,Riccardo Buccolieri,Silvana Di Sabatino +6 more
TL;DR: In this paper, the authors investigated pollutant removal at pedestrian level in urban canopy layer (UCL) models of medium packing density using computational fluid dynamics (CFD) simulations.
Journal ArticleDOI
Integrated impacts of tree planting and street aspect ratios on CO dispersion and personal exposure in full-scale street canyons
Hongyu Yang,Taihan Chen,Yuanyuan Lin,Riccardo Buccolieri,Magnus Mattsson,Ming Zhang,Jian Hang,Qun Wang +7 more
TL;DR: In this paper, the influence of tree plantings on urban airflow and vehicular CO exposure in two-dimensional (2D) street canyons with various aspect ratios (building height/street width, AR=H/W = 0.5, 1, 3, 5) and ground-level source was investigated.
Journal ArticleDOI
Scaled outdoor experimental studies of urban thermal environment in street canyon models with various aspect ratios and thermal storage.
Guanwen Chen,Dongyang Wang,Qun Wang,Yuguo Li,Xuemei Wang,Jian Hang,Peng Gao,Cuiyun Ou,Kai Wang +8 more
TL;DR: This study provides direct evidence in how man-made urban structures influence urban climate and also suggests the possibility to control outdoor thermal environment by optimize urban morphology and thermal storage.
Journal ArticleDOI
The influence of aspect ratios and solar heating on flow and ventilation in 2D street canyons by scaled outdoor experiments
TL;DR: In this article, the authors performed scaled outdoor measurements to examine the relative role of wind-driven dynamic force and buoyancy force by non-dimensional buoyancy parameter B within two-dimensional (2D) street canyons in SOMUCH (Scaled Outdoor Measurement of Urban Climate and Health).
Journal ArticleDOI
A zonal model for assessing street canyon air temperature of high-density cities
TL;DR: In this paper, a zonal model was developed to assess airflow and air temperature in street canyons in high-density cities, taking into account 3D urban geometries, external wind, buoyancy, convective heat transfers from urban surfaces; it can simulate zonal air temperature, pressure, and airflow patterns by interactively solving mass, pressure and energy balance equations.
