摘　　要：通过理论分析得出了无喷淋中庭火源的火焰气流各分区的高度范围及烟气温度随中庭高度的变化趋势。在模型中庭内进行了发烟实验,得到了在自然状态、上送风、下排烟和上送下排状态下烟气温度随模型中庭高度的变化曲线。实验结果与理论结果的对比表明,在湍流区二者偏差不大。Explores the height range of fire source subareas for the atrium without sprinkling devices and the changing trend of smoke temperature with atrium height by theoretical analysis. Obtains the relationship curves of smoke temperature with the height of model atrium by smoke tests under natural ventilation, supply air in upper zone, exhaust smoke in lower zone and combined with upper supply and lower exhaust conditions. A comparison shows that there is minor deviation between the experiment results and theoretical analysis results.
