本文给出一种模型燃气轮机燃烧室中三维气相反应流流场的数值计算结果。计算中采用了著名的SIMPLE算法,改进的κ-ε双方程湍流模型及湍流扩散燃烧模型。研究了燃烧过程对流动图形的影响。计算结果经过实验验证,两者符合较好。
In this paper, a numerical calculation of the flow field of a three-dimensional gas-phase reaction flow in a gas turbine combustor is given. The well-known SIMPLE algorithm, modified κ-ε two-equation turbulence model and turbulent diffusion combustion model are used in the calculation. The influence of combustion process on the flow pattern was studied. The experimental results show that the two are in good agreement.
