侧吹风对建筑外立面窗溢流流动的影响

摘要

以高层宾馆为例,通过理论分析和数值模拟的方法分析不同火源功率、不同侧吹风风速作用下建筑外立面窗溢流的温度分布、倾斜角,研究窗溢流的流动特性.通过理论分析得到了侧吹风作用下窗溢流倾斜角的计算式.倾斜角的模拟值与计算式的预测值符合较好.%Taking a high_rise building hotel as example, by theoreti-cal analysis and numerical simulation, the temperature distribution and inclination angle of the window plume along the exterior wall of the building were studied. The flow behavior of window plume was discussed. The calculation formula of inclination angle of the window jet plume was obtained by theoretical analysis. The simula-tion results and the calculation results of inclination angle were in good agreement.
