摘要:
为了更准确的预测和判断画布类材料的竖向着火过程,减少此类事故的发生,保障劳动者生命财产安全,根据Quintiere等人提出的热物理模型,推导出火焰沿竖向蔓延的数学规律。通过对画布材料的实验研究并与火灾动力学软件FDS数值模拟得出的结果进行比较,得出其在竖向燃烧的相关参数。重点研究了火焰形态、火焰高度、火蔓延速度、油画布表面温度、质量损失速率和热释放速率,得到了油画布的火灾增长系数为0.1228。实验表明,画布的竖向燃烧速度远远大于其在水平方向的速度,因此在全景画馆中的火灾危险性是非常突出的。
Abstract:
In order to accurately predict and judge the vertical ignition process of canvas type materials,thus reduce such accidents and protect life safety of worker,according to the thermal physical model proposed by,and deduced the spread mathematical laws of flame along the vertical direction were doluced.Through the experimental study on canvas material and comparing with numerical simulation by fire dynamics software FDS,the results of related parameters in the vertical combustion were obtained.Key research on the flame shape,flame height,fire spread speed,canvas surface temperature,mass loss rate and heat release rate were conducted,and the canvas 0.1228 coefficient for the fire growth was obtained.Experimental results showed that the combustion rate of vertical canvas was far greater than that in a horizontal direction,so the role of the fire hazard in panorama ACTS was very outstanding.
