摘要:
运用化学动力学计算软件Chemkin III中的Senkin程序包以及Chemkin 3.7中的Premix程序包,建立巷道内瓦斯爆炸过程的计算模型,其化学反应采用美国lawreuce Livermore国家实验室甲烷燃烧化学动力学详细反应机理,包括53种组分和325个反应.利用此模型对巷道内瓦斯爆炸过程中反应物及爆炸后部分致灾性气体体积分数的变化趋势进行数值计算,分析巷道中空气含湿量对瓦斯爆炸的抑制机理.结果表明,反应过程中活性分子(OH、H、O)的体积分数是影响瓦斯爆炸以及爆炸后部分致灾性气体生成的关键因素;混合气中的水蒸汽对瓦斯爆炸及爆炸后CO、CO2、NO和NO2的生成起抑制作用,随着空气含湿量的增加,该抑制作用得到加强.
Abstract:
By using the Senkin code of Chemkin III and the Premix code of Chemkin 3.7 chemical kinetics packages, the computational model of gas explosion in a coal mine tunnel was built, and the detailed reaction mechanisms (including 53 species, 325 reactions) were adopted. The variation trend of the volume fractions of reactants and catastrophic gases after explosion in the tunnel of a coal mine was simulated by this model. Furthermore, the inhibition mechanism of humidity ratio of air in the gas explosion was analyzed. The results show that the volume fractions of active species (such as OH, H, and O) are the key factors that affect the process of gas explosion and the formation of catastrophic gases after explosion. The water in the mixed gas will inhibit the process of gas explosion and the formations of CO, CO2, NO and NO2. At the same time, with the humidity ratio of air increasing, the inhibition effect will be enhanced.
