摘    要:
运用化学反应动力学理论,采用详细的瓦斯爆炸反应机理,分析了封闭空间内水及CO2对瓦斯爆炸反应动力学特性的影响。在4种工况条件下,通过数值模拟的手段,分析对比了水及CO2对瓦斯爆炸过程中温度、压力、反应物浓度、自由基浓度以及爆炸过程中生成的部分致灾性气体浓度等变化趋势的影响,找出了水及CO2对瓦斯爆炸反应动力学特性影响的异同。结果表明:CO2在降低瓦斯爆炸的强度方面比水的效果好。

关 键 词:瓦斯爆炸  化学反应动力学  反应机理  数值模拟  反应器

Abstract:
The chemical reaction kinetics theory,detailed gas explosion reaction mechanism and numerical analysis method were used to analyzed the impact of water and CO2 on gas explosion reaction kinetics in enclosure space.In the four working conditions,through numerical simulation,the impact of water and CO2 on the trends of the temperature,pressure,concentration of reactants,radicals concentration and fractions of catastrophic gases of explosion were analyzed in enclosure space,and got the differences of the impac...
Keywords:gas explosion  chemical reaction kinetics  reaction mechanism  numerical simulation  reactor
