大气防疫风环境模拟下探究传统街巷尺度对风环境的影响
Study on the Influence of Traditional Street Scale on Wind Environment under the Simulation of Atmospheric Epidemic Prevention Wind Environment:A Case Study of Yaoyaqian Block in Ganzhou City
摘要
Abstract
In the post-epidemic era,epidemic prevention and control has entered the stage of normalization.However,some"traditional streets"with history and culture have common problems,such as compact building layout and dense population,which pose great hidden dangers to the ventilation requirements of epidemic prevention.In order to improve the wind environment quality of traditional historic blocks and effectively inhibit the spread of viruses,this study took Yaoyaqian Historic Block of Ganzhou City as an example.Based on CFD technology and Swalvent software,this study simulated the air epidemic prevention wind environment of historic streets and streets in Yaoyaqian City of Ganzhou City,and analyzed the influence degree of four factors of street height,width,length and ground roughness on wind environment.According to the simulation results,the weight order of its influence on wind speed is as follows:street height>width>length>ground roughness,and the street scale is 2-4m in width,3-6m in height,40-80m in length,and ground roughness is 0.5-0.75,the wind speed in the street is the most influential.It is hoped that some measures can be adopted to optimize the ventilation capacity of streets and alleyways to inhibit the spread of the virus in the later stage of the transformation of the traditional historical streets and alleyways.关键词
