摘要
介绍了利用CHEMKIN 4.1软件中封闭的全混同性反应器模型模拟加湿情况下氢氧燃烧的方法,同时基于详细的氢氧燃烧化学反应动力学机理分析了初始反应温度、反应压力及水蒸气添加量等对氢氧燃烧的影响。模拟结果表明,初始反应温度、反应压力及水蒸气添加量等因素均会对氢氧燃烧的点火延迟时间和燃烧最高温度产生一定程度的影响,其中水蒸气添加量的变化对氢氧燃烧的最高温度及火焰传播速度的影响较为显著。这对后续在实验室中进行氢氧加湿燃烧研究可提供有益的指导。
A way using closed homogeneous batch reactor（CHBR） model in CHEMKIN4. 1 software to simulate the humidified combustion of hydrogen-oxygen mixture was described. The influences of initial reaction temperature, reaction pressure and the addition amount of water vapor on combustion of hydrogen-oxygen mixture were analyzed based on detailed chemical kinetic mechanism of hydrogen the initial reaction temperature, reaction pressure and the of influences on the ignition delay time and the maximum combustion. Simulation results showed that factors such as addition amount of water vapor will exerte certain amounts temperature of hydrogen combustion, and the variation a- mount of water vapor has a more significant influence on the maximum temperature and flame propagation speed of hydrogen combustion. This provides useful guidance for further studies of the humidified combustion of hydrogen-oxygen mixture in the laboratory.
