Abstract Body

With the acceleration of urbanization, the air quality of many cities is worrying. The improvement of wind environment can effectively promote the diffusion of air pollutants and inhibit the formation of urban heat island effect. This study intends to study the coupling relationship between wind environment and block shape through parametric study of urban residential block form and CFD (Computational Fluid Dynamics) simulation method. The project selects 10 typical residential forms in Beijing, and classifies them into groups for the morphology parameterization. Combined with the local environment, the wind environment of different residential areas is evaluated. According to the simulation results, the wind environment of different altitudes of each group of models is statistically analyzed. The morphological characteristics of urban residential block forms are summarized, which are conducive to the reduction of air pollutants, and scientific planning suggestions and reference for the future urban residential blocks with a good ventilation environment are given.
