Evaluation of Street Wind Environment in Shanghai Based on Computational Fluid Dynamics Numerical Simulation Under Typhoon Background

Abstract:

This paper， using Xuhui District of Shanghai as a representative of urban areas and Jinshan District as a representative of suburban coastal areas， analyzed meteorological data from the perspective of street trees， focusing on the maximum wind speed and direction during periods of high typhoon frequency. Then， it inputted these basic data into CFD（computational fluid dynamics） simulations to model the wind environment of the study area. Afterwards， it evaluated the “wind-tree” ecology of the streets based on wind speed grades， street orientation， and the road greening structure. Finally， it obtained the comprehensive evaluation results of the wind environment in the targeted areas.
