Research on Urban Wind Environment: Technology Evolution and Integration of Evaluation Systems
Yang JZhang TTan Y
With the increasing urbanization and density of urban space, urban wind environment became one of the focuses of multidisciplinary research. The wind environment plays an important role on all the diffusion of air pollutants, heat island effect, and thermal comfort perception of open space. This article reviews the oversea studies on technical evolution and evaluation system construction of urban wind environment. Analyzes the evolution of its technology research in field measurement research, physical simulation research, and computer numerical simulation research. Then integrates the existing urban wind environment evaluation system features. These related technical methods can play a positive supplement in urban planning.
