Microclimate Analysis For Xi’an City Spuare And Street Space Influenced By Airflow Micro-circulation

Xi’an urban square and street space for outdoor activities is a resident of the basic properties, which reflect the microclimate effects of climate adaptation, has a significant impact on the residents of climate comfort during outdoor activities. Airflow microcirculation is an essential element of urban outdoor space environment microclimate in order to study the airflow microcirculation starting point to explore the city of Xi’an microclimate effects of outdoor space, to improve its efficiency and enhance the residents of outdoor activities is important for climate adaptation.For the study of Xi’an outdoor space microclimate airflow microcirculation mechanism, resear urban outdoor space air movement basic model, determine the cause of the airflow movement and general movement when hampered by the single building and plant, street canyon environment for wind environment were focused on research, determining the difference of air movement after encounter different aspect ratios street canyon, discrimination block canyon airflow after heat; research hot ventilation principle and its application in traditional buildings, underground construction and industrial building design.Xi’an different types of small squares and street space weather effects test to analyze the airflow microcirculation movement rules and mechanisms.Select Dayan Pagoda South Square which has typical characteristics as the main object of study, accord method of CFD simulation and square space hot-cold partition, research different partition internal airflow,comparative analysis of the summer and winter seasons microclimate test wind environmental differences; select Dayan Pagoda North Square as a comparative study, analysis of different scale and spatial differences in morphology square space wind environment, Xi’an city Square airflow drawn microcirculation general action rule. Select Qingnian Road and Shuangrenfu Road as a single space fully enclosed street research object, combine CFD simulation and street microclimate test data, analysis the overall wind street type environment, and select typical cross-section analysis airflow microcirculation movement.Through Xi’an urban outdoor space microclimate effects test and test analysis, make climate adaptive design strategies.
