摘要
为获得某型导弹在测试厂房内发生推进剂泄漏后,推进剂蒸发产生毒气的扩散规律,开展了测试厂房通风条件对偏二甲肼泄漏蒸发形成蒸气的扩散过程数值研究,分析了通风风速5m/s时,测试厂房内有毒气体的浓度分布情况,以及不同进风风速、进风方向对偏二甲肼蒸气扩散的影响。研究结果表明,在所设定的泄漏状态下,通风系统以5m/s进风风速和水平进风风向工作时,有利于室内偏二甲肼蒸气的排出。
In order to obtain the rule of toxic gas dispersion caused by unsymmetric dimethyl-hydrazine vaporization after leaking in a missile testing hall,the author conducts numerical study on the disperse process of vapor formed by leaked unsymmetrical dimethylhydrazine under ventilation condition of the testing hall and analyzes concentration distribution of toxic gas under the air velocity of 5 m/s as well as influence of different speeds and directions of inlet air on dispersion of unsymmet-rical dimethylhydrazine.The study result shows,under this leaking conditions,there is better emis-sion of indoor unsymmetrical dimethylhydrazine vapor when ventilation system works with horizontal air inlet and at air velocity of 5 m/s.
