| 摘 要： | 为了探究密闭空间内通风对气体泄漏扩散过程的影响，基于FLACS模拟软件，对密闭空间内CO2泄漏及排散过程进行模拟，探讨入风口、出风口相对位置对泄漏及排散过程的影响。研究结果表明:入风口高度与出风口高度越高，越有利于CO2气体排散，应急排散时间更短；入风口位于屋顶时，CO2排散效果最好。

| Abstract: | In order to explore the influence of ventilation on the gas leakage and diffusion process in the enclosed space,the CO2 leakage and dispersion process was simulated by the FLACS simulation software,and the influence of the relative positions of air inlet and air outlet,on the leakage and dispersion process was discussed.The results showed that the higher the air inlet height and air outlet height,the more conducive to CO2 dispersion,and the shorter the emergency dispersion time.The CO2 dispersion effect was the best when the air inlet was located on the roof. |
