| 本文是国家科技进步重点项目"失火中庭烟气控制"(No-98-04-03)的一部分。文章采用正交实验法,对影响中庭机械排烟过程中烟气层高度的排烟量,火源释热速率,排烟口及排烟口各因素之间的交互作用等因素进行了研究。实验表明:排烟量大小,排烟口数量和火源释热速率对烟气层高度的影响特别显著;排烟口间距,排烟口间距与数量的交互作用以及排烟口位置对烟气层高度有明显影响;排烟口大小,排烟口数量与位置,数量与大小,间距与位置,间距与大小,位置与大小之间的交互作用的影响不明显。 |
| 英文摘要: |
| This is a part of the project, Smoke Management in Atria under Fire, which is the advanced project of the National Science and Technology. Orthogonal experimental method is employed to study the effects of some factors on the smoke layer interface. The results of orthogonal experiment shows that the effect of the volumetric flow rate of exhausted smoke is the most notable; the effects of the number of exhaust inlets and the heat released rate of fire source are less notable than the effect of the volumetric flow rate of exhausted smoke on the smoke layer interface; the effects of the interval between exhaust inlets, the interrelation between the number of and the interval between exhaust inlets and the location of exhaust inlets are notable; but the rest factors’ effects are not obvious. |
