摘要
使用CFD软件模拟在居住建筑单室中,相同开窗面积、相同位置的矩形窗口,不同开窗比例对室内自然通风效果的影响,定量分析比较了不同开窗比例下室内风环境的各种参数,发现这些参数都随着开窗宽高比的增大而呈有规律的变化.通过比较分析得出：在相同条件下,当开窗的宽高比在2.0～2.6时,室内自然通风效果最好.
The CFD software is used to simulate the rectangular window with same windowing area and position in the single room of the residential building and the influence of different windowing proportion on the indoor natural ventilation effects, carry out the quantitative analysis and comparison of various parameters of indoor wind environment under different windowing proportion, and find that these parameters show a regular change with the increase of windowing aspect ratio. Through the comparison and analysis, the indoor natural ventilation effects are best when the windowing aspect ratio ranges from 2.0 to 2.6 under the same conditions.
