摘要
窗对于住宅的自然通风影响很大,开窗可以使室内产生较大的室内平均风速,并且窗台高度、窗的尺寸、窗的水平相对位置对室内流场都有一定影响。利用计算流体力学(CFD)软件,采用室内平均风速作为参考量,分别分析在贯穿通风和单侧通风的情况下,不同窗台高度下,不同尺寸的窗(窗面积相同),风进入窗的不同角度对于室内通风量的影响。
Windows exert great influences on natural ventilation of residences. Opening of windows will accelerate overall indoor airflow; besides, the height of windowsills, dimension of windows and relative horizontal location of windows will affect indoor flow field. Using the CFD software and adopting the indoor average wind velocity as the reference quantity, the thesis analyzes the influences on indoor air quantity on the conditions of different heights of windowsills, different dimensions of windows （with the same window area） and different angles of ingoing wind respectively in through ventilation and single-side ventilation.
