Based On Cfd Technology, Urban Climate Modeling And Climate Adaptation Planning Strategy

Wind is the dominant factor that affect the thermal environment, Heat, is the most intuitive experience for urban climate and environment. Good urban wind environment can discharge urban heat to improve the thermal environment, the urban planning has a great influence on the operation of wind environment. Therefore, analyzing interrelated effects among urban wind environment, thermal environment and the urban is important direction that explore climate adaptation for urban planning program, Good urban space and the design of livable conditions play the role of improving the urban microclimate, however,good urban micro-climate that is the important path of establishing sustainable development of eco-city is conducive to improving thermal comfort of the urban environment and contribute to achieve the goal of building and urban energy conservation.In this paper, as a support to the urban climate-related theory, as a means to CFD technology, chosen the center district of Changsha in summer as study object and established a model in urban areas of Changsha, On the implementation of the planning is not to simulate the urban environment by the idea, the planners a new way to understand the planning program. The simulation program is to explore and grasp the understanding of urban elements of the relationship between the urban environment.Analysis of the central city air, hot climate distribution. Summarized the existing downtown urban climate in the distribution of the urban environment, looking for contradictions lie. In Urban Climate and Urban summarized the elements of the interaction mechanism based on the proposed exploration of urban planning climate adaptation strategies, formed through the application of strategic planning, and use simulation to verify.The idea make a new way to planners for understanding plannings programs,that take the unrealized planning as model to make simulate. and also go further in exploring the relationship between urban elements and climate to make urban climate healthier, safer and more comfortable.
