Research On Outdoor Wind Environment Characteristics And Optimization Strategies Of Universities In Southern Hebei Province

With the vigorous development of infrastructure and improvement of living standards in China,ecological environment and resource allocation issues are becoming increasingly prominent.With rapid urbanization,building energy consumption and infrastructure supply are growing,while satisfaction with the environment is declining.The outdoor wind environment of campus is an important aspect of external space comfort.At present,the research on the comfort of external space in Ji’nan region is mainly in urban parks and traditional villages,and the research on the comfort of outdoor wind environment of universities needs further exploration.Based on this,the study is based on improving the current situation of wind environment of colleges and universities in southern Ji’nan,using literature analysis,field research,CFD(computational fluid dynamics)method and control variable analysis as samples of wind environment of five representative colleges and universities in southern Ji’nan,analyzing the spatial structure of campus,summarizing the characteristics of current wind environment,and analyzing the outdoor wind environment of colleges and universities and campus design at the level of building monolith,building space group and campus planning respectively.We analyze the correlation between outdoor wind environment and campus design elements,and provide a theoretical basis for the optimization strategy of outdoor wind environment of colleges and universities in southern Ji’nan.Firstly,the research progress of wind environment of buildings at home and abroad is reviewed and analyzed based on Citespace and Research Rabbit,and the main content of the thesis is proposed.Secondly,the simulation analysis of outdoor wind environment in winter and summer conditions is carried out for the current situation of Ji’nan University,and the characteristics and problems of the current wind environment are summarized and compared with the actual wind environment measurement and the current simulation to verify the accuracy and feasibility of numerical simulation.Secondly,the correlation analysis between outdoor wind environment and campus design elements of colleges and universities in southern Ji’nan is discussed at the level of building units,spatial layout of building groups and campus planning and design respectively.Finally,the optimization strategies and application practices of outdoor wind environment of colleges and universities in southern Ji’nan are summarized.Firstly,the principles of "locality","comfort","health" and "synergy" are proposed for the optimal design of campus wind environment.The principles of "locality","comfort","health" and "synergy" are proposed.Secondly,the optimization strategies are proposed at the level of new campus planning,building groups and individual buildings.According to the optimization strategy,the new campus of Hebei University of Engineering is used as an example for simulation and verification,and a comparative study is conducted with the current wind environment.The results show that the comfortable wind area under the optimized summer conditions increases by 14.66% and the static wind area ratio decreases by 0.50% compared with the current situation;the comfortable wind area ratio under the winter conditions increases by 2.26% and the static wind area ratio decreases by 0.17%.Therefore,it is sufficient to prove that the optimization strategy proposed by the study can effectively improve the shortcomings of the current wind environment and improve the comfort of the wind environment in the external space,which can provide an optimization strategy and suggestions for reference for the optimization design of outdoor wind environment in the universities in the southern region of Ji’nan.
