Research On The Optimization Strategy Of Urban Design In The Surrounding Area Of Urban Ventilation

With the speeding up of the process of urban construction,urban heat island effect,air pollution is the major problems affecting the urban environment.From the perspective of the urban climate and urban wind environment research,found that optimization of urban ventilation is an effective means to improve the urban environment.Build cities ventilation has also been more and more applied to the practice of specific planning.But at present most of the urban design based on visual and spatial experience,fresh general ventilation as consideration,ignored the ventilation efficiency of the security problem.This article in order to improve the ventilation efficiency as the core,significantly affect the ventilation efficiency of the ventilation duct width,vents architectural layout,skyline contour and exploration on the three factors to the urban design?By PHOENICS software simulation analysis,the paper puts forward Urban design optimization strategy on ventilation surrounding area.urban ventilation area surrounding the optimization strategy of urban design.Taking the above mentioned points as the starting point,the thesis attempts to put forward the optimization tactics of the urban design around city ventilation channel area.Specifically,the research content is divided into six chapters.First chapter is an introduction of thesis research background,purpose,theoretical basis and research present situation.In addition to the introduction of the basic principle of urban ventilation design,the main factors influencing the ventilation efficiency,the evaluation standard,The second chapter also introduces the necessity of the research and tries to provide theoretical basis for the effect of urban design on the ventilation effect..The third chapter introduces the usage of the PHOENICS software,providing technical support for later analysis.Through the establishment of ideal model and using the software analysis,the fourth chapter puts forward influential factors on in the design of air duct neighboring area city,and.Chapter v puts forward advice and methods in view of the problems of ventilation problem of the specific area based on empirical study and the above research.The Sixth chapters summarize the research work and the conclusion,and puts forward the research deficiency and limitation and the prospect of the research is forecasted.
