Studies Of The Urban Leisure Blocks Microclimate Environmental

With the city’s rapid economic development, people’s living standards quickly improve, people’s pursuit of quality of life improved, the people who are living in the city, hoping to have their own place to relax, the casual neighborhood has naturally become the focus of attention. So the following research carried out " The width of the alley" as a example to study the urban casual neighborhood outdoor microclimate environment.1、In order to understand the basic situation of casual neighborhood outdoor microclimate, In the width of the alley I conduct field research in three different places with WBGT measurement instruments to measure. and summed up the basic situation of the microclimate variation in the width of the alley within a certain time frame.2、Take advantage of ECOTECT to study the width of the alley outdoor thermal environment details sunshine shelter analysis and solar radiation simulation analysis. And take a further analysis to sunshine spacing, building orientation and layout of the building. By providing a detailed analysis of the data and analysis chart, make up the inadequacies observed without simultaneous measurement of three points. finally, horizontal contrast to the thermal environment and the overall width of the alley, summed up the pros and cons of the thermal environment of the width of the alley.3、BY using FLUENT software, the unique, complex and changeable Urban wind environment summed up the basic simulation of atmospheric boundary layer in the gas flow in the city system. In addition, in order to more accurately simulate the plant canopy air flow impediment, I based on the theory of porous media, the innovative utilize leaf area to calculate the correlation coefficient of the plant canopy in the wind environment simulation, and predecessors the wind tunnel experiments compared the efficacy and verify the analog system more reliable. Finally, this paper proposed wind environment simulation system for buildings and plants, wind environment simulation analysis to the width of the alley as a example, provides a basic example of the outdoor wind environment simulation analysis for the study of reference.The papers laid the foundation for accurate forecasting and objective evaluation of urban leisure neighborhoods outdoor microclimate environment, the paper proposed thermal environment simulation analysis system wind environment simulation analysis system makes utilize computer simulations to guide and optimize urban casual neighborhood outdoor microclimate became possible.
