本文阐述了以 SIMPLE 算法为基础的燃气轮机燃烧室流场的数值计算方法,对一实例燃烧室作了计算并与冷态实验进行对比。结果表明:回流区的主要尺寸两者数值相当吻合;轴向与切向速度分布规律也是接近的,只是在数值上略有差别。本计算方法在预测燃烧室流场上具有一定的实用价值。
In this paper, the numerical calculation method of gas turbine combustor flow field based on the SIMPLE algorithm is described. An example combustion chamber is calculated and compared with the cold state experiment. The results show that the main dimensions of the recirculation zone are in good agreement with each other. The distribution of axial and tangential velocities is also close, but only slightly different in value. The calculation method has certain practical value in predicting the flow field in the combustion chamber.
