| 摘 要： | 为合理考虑湍流-复杂化学反应的相互作用,建立了甲烷湍流四步反应的温度脉动简化概率密度函数(PDF)模型.应用该模型对TECFLAM燃烧室内的甲烷湍流旋流燃烧进行了数值模拟,得到了与实验相符合的气体轴向、径向与切向速度、温度、温度脉动均方根值及甲烷、氧气、二氧化碳与水蒸气质量分数分布.得到的一氧化碳和氢气质量分数分布与实验基本符合.

| Abstract: | To account for the interaction between turbulence-complex chemical reactions,a presumed probability density function(PDF) model for temperature fluctuation is built to simulate four-step reaction of methane turbulent in the present paper.The model is applied to numerical simulation of methane swirling turbulent combustion in the TECFLAM combustor.The calculated results agree with the measured test data in terms of the distributions of gas axial,radial,and tangential velocities,temperature,and fluctuating te... |
