| 摘 要： | 以普通的居民住宅为研究对象,考虑室内燃气泄漏的特点,利用计算流体动力学,通过Fluent模拟软件对室内燃气泄漏后的扩散情况进行二维模拟。分析室内燃气泄漏扩散情况。结果表明:(1)点火源1在295 s左右时达到爆炸极限;(2)厨房门开启时,点火源2在14 316 s时达到爆炸极限;关闭时,点火源2达到爆炸极限的时间很长。

| Abstract: | Based on the Ordinary residential buildings as the research object, considering the leakage characteristics of indoor gas, using computational fluid dynamics, Fluent simulation software is used for 2d simulation of leakage and diffusion of indoor gas, the leakage and diffusion of indoor gas is analyzed. The results show that: (1) the ignition point 1 in about 295s reaches the explosion limit; (2) when the kitchen door is opened, the ignition point of 2 in 14316s reaches the explosion limit; when it is closed, the ignition point 2 reaches the explosion limit for a long time. |
