| 摘 要： | 详细介绍了小尺寸烟气迁移实验台,并在此实验台上开展了一系列烟气从狭长走廊向远距离非火源房间迁移的实验研究.狭长走廊的两端封闭,烟气只能从非火源房间出口处排出.研究表明,狭长走廊和非火源房间之间的开口大小对于远端非火源房间中的烟气危害性影响非常大.在非火源房间同一高度设定测点,当开口较小的时候,测点处的烟气浓度处于低水平震荡状态,随着开口尺寸的增大,震荡趋势逐渐衰减,烟气浓度峰值成倍急剧攀升.同时发现,特定时间段中出现靠近走廊远端测出的烟气浓度高于靠近火源房间的烟气浓度的现象. |

| Abstract: | ement of the opening size. Meanwhile, it was found that the smoke concentration at the sampling point in the remote room is higher than in a room close to the fire-origin room in a given period. |
| Keywords: | reduced scale hallway remote room smoke opening size |
