| 摘 要： | 以竖向可燃材料PMMA 为例，采用FDS 软件研究正交实验设计下的喷淋特征参数（喷淋流量、喷淋角度）对竖向温度场的影响，运用直观分析法、方差分析法、因素指标分析等方法分析影响规律。实验结果表明，喷淋流量的增大和喷淋角度的增大可以有效抑制材料燃烧；增加喷淋流量所造成的抑制效果，大于增加竖直喷淋角度或水平喷淋角度造成的抑制效果。

| Abstract: | Taking vertical combustible material PMMA as an example,the FDS software was used to study the influence of spray characteristic parameters(spray flow,spray angle)to the vertical temperature field under vertical orthogonal design.The visual analysis method,analysis of variance method and factor index were used to study the rules of influence.The experimental results showed that,increasing the spray flow and the spray angle can effectively suppress the material combustion;the suppression effect caused by increasing the spray flow is greater than the suppression effect caused by increasing the vertical spray angle or horizontal spray angle. |
