| 摘 要： | 木材着火时火焰的传播规律将为木材在火灾场景中的行为提供重要参考,分析了木材燃烧的机理和影响木材燃烧时火焰传播速度的特征量,借助于实验的方法,研究了空间方位角和几何尺寸等特征量对火焰传播速度的影响.结果表明,方位角越小,不同尺寸木条火焰传播速度差别越大;火焰传播速度随方位角的增大而增大;木条宽度越大,火焰传播速度越慢.

| Abstract: | The law of flame spreading speed of wood can offer the significant reference for the behavior of wood in fire accident. Mechanism of wood burning and characteristic parameters influencing flame spreading speed in wood were studied in the paper. The orientation angle and geometric size influencing flame spreading were investigated in experiments. The results show that the smaller the angle of orientation the bigger the differences in speed of flame spreading in wood with different sizes.The speed of flame spreading in wood increases when orientation angle increases.The speed of flame spreading decreases as width of the wood strips increases. |

| Keywords: | flame spreading speed angle of orientation geometric size combustion |
