摘要：

By performing wind tunnel model measurements and CFD flow simulations in a designated region at Banqiao District, the local pedestrian thermal comfort was assessed. At the beginning, pedestrian wind speeds at selected locations of a 1/250 scaled model were measured and the results were used to guide and confirm those from the simulations. The results of numerical predictions were then used to perform pedestrian comfort analyses in the designated region. Results showed that CFD could be applied to provide fairly acceptable prediction wind environment data in help with the execution of thermal comfort analyses. Moreover, a procedure of thermal comfort assessments was demonstrated by an integration of the available methods from the previous related studies. In future urban planning, accordingly, similar wind environment analyses should be carried out before the reconstruction in the aged buildings area as thermal comfort is concerned. © 2019, Chinese Institute of Civil and Hydraulic Engineering.
