摘要: 摘 要:  燃气属于易燃易爆的危险性气体, 当在室内有限空间发生泄漏时, 会带来相当严重的后果。针对燃
气泄漏扩散的特点, 利用G a m b i t建立室内燃气灶喷嘴处气体泄漏扩散的物理模型, 并结合 C F D流体动力学软件
F LUENT模拟了燃气连续泄漏的扩散过程。对燃气在一定温度梯度、 不同湿度条件下的扩散效果进行了对比, 并监
测了指定安装区域内不同安装点处的浓度, 以期达到优化报警器安装位置的目的。结果表明, 室内空气的相对湿度
和安装位置是影响报警时间的关键因素; 在相同安装点, 当空气相对湿度增加1 5%时, 报警时间延迟近6s ; 在一定
的空气相对湿度下, 报警器距离泄漏口水平位置增加1m, 报警时间滞后4s 。

关键词: 泄漏扩散, 相对湿度, 安装位置, 燃气报警器, 优化

Abstract: Gas belongs to flammable and explosive hazardous gas. When the leakage of gas occurred in limited indoor space, the serious consequences would be produced. According to the characteristics of the gas leakage diffusion, firstly Gambit was established indoor gas stove nozzle dispersion physical model. Secondly CFD fluid dynamics software FLUENT was used to simulate the diffusion process of continuous leakage. Finally comparing the diffusion results under certain temperature gradient but different moisture conditions, and monitoring the specified installation area with variety of mounting points, the aim was to optimize the installation position of the alarm. The results show that the location of distance and relative humidity of indoor air were both the key factors on affecting the alarm time. For the same mounting points, relative air humidity increasing 15% would cause delaying the time of alarm nearly 6 s| under the same air relative humidity, each time the alarm was away from the leaking mouth increasing by 1metre, alarm time would lag for 4 s.

Key words: Leakage diffusion, Relative humidity, Installation position, Gas alarm, Optimization
