| 摘要: |
| 为掌握竖通道内火旋风热流场温度特性,利用数值模拟方法对竖通道内火旋风中轴线上温度进行研究.通过将数值模拟结果和实验数据对比,验证了构建的数学模型对有侧开缝的竖通道内火旋风中轴线上温度模拟的准确性；基于McCaffrey油池火羽流温度分区思想,发现竖通道内火旋风羽流温度可被近似为3个被纵向拉长的区域；通过对结果的数据拟合得到了适用于竖通道内火旋风中轴线上羽流温度计算公式的各分区高度及公式中相应系数值. |

| Abstract: |
| In order to understand the temperature characteristic of fire whirls in the vertical shaft, numerical simulations were carried out to study the centerline plume temperature of fire whirls in the vertical shaft. The numerical simulation results of centerline plume temperature were verified by using experimental data. It was found that plume temperature of fire whirls in the vertical shaft can be approximately divided into three regions which were stretched in the vertical direction based on the theory proposed by McCaffrey. The height values of different regions and formula coefficients were obtained, which are suitable for centerline plume temperature of fire whirls in the vertical shaft. |
