摘要 在燃烧过程氮氧化物生成的基元反应和反应动力学基础上,推导并建立了新的NOx生成化学动力学模型,并利用流体力学计算软件及湍流模型分析手段,对天然气燃烧过程NOx生成进行了模拟计算,预测结果与实验结果吻合良好。研究表明,新模型比平衡模型和部分平衡模型预测更加接近实验结果,实现了对NOx生成数学模型的优化。 A novel chemical kinetics model was established to describe the combustion processes under the theoretical basis of elementary reaction of NOx formation and reaction kinetics. The NOx formation process was simulated by the new model with the CFD software, and the results were in good agreement with the experimental data. It can be concluded that the new established model is better than the equilibrium model and partial equilibrium model provided by the FLUENT module, when they are used to calculate the combustion processes.
