Numerical Simulation Of Wind Environment By High-rise Residential Community

With the rapid development of Chinese economy, the modernization of the city also will accelerate, various layouts and diverse, a large number of high-level rise of complex shape and high-rise buildings, wind environmental issues of safety, health, energy and other aspects of the resulting positive serious impact on people’s daily lives. High-rise residential community in the modern city as the main place people’s lives, the merits of which are related to environmental conditions more and more people are understanding and concern, and residential outdoor wind environment on outdoor thermal environment, indoor natural ventilation, the residential energy consumption so has a profound impact. How to provide a safe, healthy, comfortable, energy efficient outdoor wind environment nowadays become a hot issue in the research for community residents.To solve these problems, this paper mainly from wind angle, aspect angle buildings, building layout to study its effect on the high-rise residential community outdoor open air environment, and through a high-rise residential area of Xian’s field test to verify the accuracy of the simulation method and reliability, the specific contents are as follows:(1) From several aspects single building, group building, building blocks, the greening of the current research in terms of building wind environment were reviewed, introducing the basic theory of building residential wind environment, and describes the methods of outdoor wind environment.(2) Elaborate system of CFD numerical simulation method of building(s) based on the flow around in a high-rise residential community project in Xi’an for instance, by field measurement and numerical simulation analysis, numerical simulation method in this paper to verify the reliability and validity of using.(3) Numerical method to study the different buildings 0o-150 o opening angle of 6 kinds of impact on the architectural layout of the wind environment, analysis of air flow characteristics of the dominant wind 6 kinds of different architectural layout inside.(4) Numerical simulation of the five kinds of typical high-rise residential community in different dominant wind farm flow(determinant, echelon type, point, staggered, enclosing group), to explore the architectural planning more meaningful way of architectural planning and design more practical applicability.
