摘要(Abstract):

以上海地区气候条件为例应用RNG k-ε湍流模型,考虑不同方位太阳辐射影响,对中庭内热环境进行了数值模拟。研究了以南向主导风进入中庭对四周外窗的自然通风,并结合中庭建筑的自然通风机理予以分析。研究表明中庭内部有较好的热环境,建筑中庭外窗充分开启能大大提高居住者对室内环境的主观评价。
Thermal environment in atrium is simulated in application of RNG k-ε turbulent model as well as in consideration of solar radiation to different orientation.Natural ventilation effect through surrounding windows by the force of south dominated wind into atrium is studied combined with the analysis in mechanism.The result indicates the preferable thermal environment in atrium and increased subjective evaluation of inhabitant when building windows are fully open.
