摘要: 对突扩燃烧室这一典型工程燃烧装置内的湍流预混反应流进行了数值模拟。时平均控制方程组的封闭采用k-ε湍流输运模型和EBU-Arhenius湍流反应模型。模拟结果给出了突扩燃烧室内湍流预混反应流的气体时均流场、组分浓度场与温度场的分布。通过数值模拟结果与实验的比较对EBU-Arhenius模型进行了讨论与评价。

Abstract: The premixed turbulent reacting flow in an axisymmetric sudden-expansion combustor has been numerically simulated. The k-ε turbulent transport model and the EBU-Arrhenius turbulent reaction model are utilized for the closure of the time-averaged governing equations. The calculated results cover the time-averaged gas flow field, species mass fraction and temperature distributions for the premixed reacting flow in the sudden-expansion combustor. The EBU-Arrhenius model is discussed and evaluated based on the comparisons between the calculated results and the measured data.

Key words: premixed turbulent reacting flow, numerical simulation, sudden expansion combustor
