| 摘 要： | 采用适体坐标法和空度法描述了排气缸复杂 的结构，开发了排气缸三维网格自动生成软件。以数值模拟为手段，描述了透平低压排气缸内部复杂的三维可压缩湍流流场。编制了三维可压缩湍汉流场数值模拟软件，采用模型吹风试验校核了数值模拟结果，为排气缸的设计提供了新的途径。

| Abstract: | The complex structure of exhaust hood is described by body fitted coordinates and porosity. Automatic grid generation technique of exhaust hood is developed. Numerical results are obtained for the three dimensional compressible flow field of low pressure turbine exhaust hood. Comparison with experimental data shows that numerical procedure is satisfactory. |
