Through the study for the full 3-d flow field of LP casing under all conditions, the internal flowing mechanism of the turbine shall be known clearly to optimize the design of air cooling units.
通过分析研究低压缸全工况三维流场，可深入了解透平内部流动机理，有助于进一步优化空冷机组设计。

The results also show that the matching of turbine and strut is not perfect, but the flow direction is still close to axial through it.
数值模拟的结果还表明：涡轮与支板的匹配不太理想，但气体通过支板后，仍能够接近轴向出气；

A method to improve the efficiency of the turbinethrough-flow passage using the technique of boundary layer suction is introduced.
