某重型燃气轮机燃烧室燃烧流动的数值模拟

Numerical simulation of combustion flow on a heavy gas turbine combustor

对某重型燃气轮机燃烧室燃烧天然气进行数值模拟,在模拟过程中采用了雷诺应力模型、EBU-Arrheniue湍流燃烧模型和六通量辐射模型来描述其燃烧流动过程,运用FLUENT软件求解了三维流场和温场分布。计算结果能够很好地反映该重型燃气轮机燃烧室燃烧流动特点,对预测燃烧室内的燃烧流动有一定参考价值。

Three-dimensional combustion flow in a combustor of the heavy gas turbine Was studied numberically using the FLUENT software.The RSM Reynolds-stress turbulence model, EBU-Arrheeniue turbulent combustion model and six-flux heat radiation model were applied to predict the combustion process in the annular combustion.the results indicate.That the characteristics of combustion flow in the annular combustor is shown.
