Research On Optimization Strategy Of Outdoor Wind Environment Of Coastal Universities In Hot Summer And Warm Winter Area Based On Human Comfort

The coastal zone in the hot summer and warm winter area of southern China has the advantage of being close to the sea,and its rich natural resources also bring broad space for the growth and development of cities.With the rapid development of coastal cities,more coastal colleges and universities are expected to spring up in the near future to provide talent resources and intellectual support for the development of the city.As an important place for students to study,communicate and live,the quality of the external space environment of university campus has an important impact on the physical and mental health of teachers and students,life,learning and communication interaction,and the outdoor wind environment of university campus is an important evaluation content of campus space environment.In order to improve the outdoor wind environment of campus and improve the comfort of human body,this study uses CFD computer simulation technology(PHOENICS software)to simulate and analyze the outdoor wind environment of some coastal universities in hot summer and warm winter area at pedestrian level(1.5m),finds out the common problems of wind environment in campus,and explores the main influencing factors and wind environment of coastal universities According to the characteristics of the environment,this paper puts forward the optimization strategy of the wind environment suitable for coastal universities in hot summer and warm winter areas,and carries out the practical optimization of the project scheme of Shantou University East Campus(phase III)according to the relevant optimization strategies.The full text is divided into three parts and five chapters.The first part is the first chapter,which describes the research background of this paper,discusses the related literature research and related concepts at home and abroad,and defines the research object and research framework of this paper.The second part is the second chapter,which discusses the theoretical research on the outdoor wind environment of coastal campus in hot summer and warm winter area,and defines the research orientation of this paper.Firstly,the related concepts and theories of wind environment are introduced to pave the way for the following research.Then,the particularity of wind environment in coastal area is summarized and analyzed,and the existing wind environment comfort evaluation standards are summarized,and the outdoor wind environment evaluation system suitable for coastal universities in hot summer and warm winter area is established.Finally,the CFD computer simulation technology is introduced and its technical process is described.The third part is from the third chapter to the fifth chapter,which is the core chapter of the full text.In the third chapter,we simulate and analyze the outdoor wind environment of some coastal campuses,and find the problems and typical characteristics of the campus wind environment in the analysis results.The fourth chapter studies and puts forward the optimization strategy of campus outdoor wind environment suitable for hot summer and warm winter climate and coastal special geographical attributes,and establishes the strategy application system of campus outdoor wind environment design from two aspects of the built campus wind environment optimization and the campus wind environment design optimization facing the planning and design stage.The fifth chapter takes the East Campus of Shantou University(phase III)project as an example,comprehensively applies the optimization strategy of campus wind environment,and effectively forecasts and improves the outdoor wind environment quality of campus with the help of CFD simulation technology in the campus planning and design stage,so as to provide design reference for other hot summer and warm winter areas campus planning or reconstruction design,campus wind environment optimization and campus space environment quality improvement.
