| 摘 要： | 在理论分析和合理简化的基础上,建立了矿井乏风逆流氧化的一维数学模型。并采用计算流体力学(CFD)软件(Fluent)模拟了其逆流氧化反应过程,探讨了主要工况参数(如流速、当量比和半周期)对逆流氧化反应温度和反应速率的影响。模拟了半周期为30s、当量比为0.2、流速分别为0.06,0.1和0.2 m/s时温度场和反应速率的分布情况。总结出有关逆流氧化反应装置的燃烧特性以及工况参数对其燃烧特性影响的规律,对提高其燃烧效率和能源的利用率有重要作用。

| Abstract: | In this paper,based on the theoretical analysis and reasonable simplification,one-dimensional mathematical model is presented for the counter-current oxidation of ventilation air methane.The process of counter-current oxidation reaction is simulated by applying the computational fluid dynamics(CFD) software(Fluent),and the effect of the dominating working parameters(such as flow velocity and equivalence ratio and half cycle) are discussed on the temperature and rate of reaction within the counter-current ox... |
