Numerical Simulation Of Outdoor Wind Environment In A University In Changchun

With the development of society,the number of educated people continues to increase,which makes more and more students on campus.make campus buildings grow rapidly,which poses serious challenges to the quality and safety of campus buildings.the wind environment can improve air quality,save energy and protect the environment.a good wind environment is helpful to teachers and students' daily life and learning state,and can improve the comfort and safety of outdoor activities.At present,more and more scholars and designers begin to attach importance to the campus wind environment.College campus is an important part of the city.It is of great significance to study the problems existing in the campus wind environment and explore its improvement measures.In this paper,the characteristics of near-ground wind and average wind are taken as the starting point,and the related concepts such as wind environment of university campus and buildings are briefly described.This paper studies the wind environment at pedestrian height,and summarizes several common wind environment evaluation standards at present.The evaluation standard of wind environment comfort suitable for this paper is defined.Then the theory and method of numerical simulation are introduced,and the key steps in numerical simulation are described in detail Finally,ANSYS Fluent software and standard k-? turbulence model are used to simulate and analyze a campus in Changchun,and the campus is divided into four areas according to the general layout of the campus.This paper analyzes the current problems and causes of wind environment in detail,evaluates the advantages and disadvantages of wind environment according to the evaluation criteria,and puts forward the optimization scheme of wind environment problems to be solved.Through the analysis of a university campus wind environment in Changchun and summary,from the entire campus architecture design and architectural layout group optimization monomer afforest decorate etc.Put forward the strategies of the optimize the environment of the campus wind At the same time,we will use the optimization solution to a certain extent,adjust the campus of the university of architectural layout,with the optimized scheme to simulate and optimize the environment of college campus before the wind,the demonstration of the implementation possibility summary optimization scheme optimization strategy,Changchun city for the future design and construction of the campus to provide accurate effective Suggestions to improve the quality of campus environment Improve the quality of school life.
