不同来流条件下区域环境对建筑自然通风的影响

摘要

The aim of this study is to investigate the velocity change of the target building caused by the surrounding buildings,which is comparing to the field measurement.Simulation describes the pressure coefficient of the building under different wind incidences： 0°,30°,45°,60°,90°.Finally,the natural ventilation rates of five incidences are compared.Under the consideration of temperature condition,ventilation efficiency of the whole year is calculated.%本文探讨了在某住宅小区由于建筑间的相互遮挡造成的建筑周围风速变化,并结合实测外场风速进行分析。在0°、30°、45°、60°和90°的风向夹角下,模拟目标建筑表面风压的分布,对比不同条件下的自然通风通风量。结合温度条件,考虑全年自然通风通风效果。
