摘　　要：为对高层建筑下Trombe墙通道内的浮力诱导气流的流动特性进行研究,首先采用实验研究与数值模拟相结合的方法,对带有Trombe墙的二层建筑通道进行对比分析,验证模拟方法的可靠性。采用相同的数值模拟方法对24层建筑通道内的浮力诱导气流的流动状态进行研究优化。结果显示:在烟囱通道内设置三角形导流肋可改善气流流动状况,连通式通道通风效果明显优于分隔式通道。在连通式通道内,导流肋尺寸占通道宽度3/4时通风效果最好。In order to study the flow characteristics of buoyancy-inducing airflow in the Trombe wall channel in high-rise buildings,the comparative analysis of the induced airflow characteristics in Trombe wall channel in a two-story building were carried out. The reliability of the simulation method is verified by combining experimental research and numerical simulation. The same numerical simulation method was used to optimize the flow state of buoyancy-induced airflow in a 24-story building Trombe wall channel. The results show that by setting triangular guide ribs in the channel passage,air flow condition can be improved and the ventilation effect of the connected passage is significantly better than that of the separate passage. In the connected channel, the ventilation ribs have the best ventilation effect when the guide rib size is 3/4 of the channel width.
