摘要
通过对某型压气机两级半在不同抽气量下的数值模拟,定量地分析了抽气量变化对压气机性能影响规律,得出了在不同抽气量下压气机性能参数沿叶高的变化规律以及气流冲角变化的规律,为进一步的优化设计指明了方向。
Numerical simulation of two and a half Compressor with air - extraction is carried out with different amounts of air-extraction. This paper analyzes the change of compressor＇s aerodynamic performance, and gives results with fixed quantity, and gets the results of variation of compressor performance along blades height in detail, in different amounts of air-extraction. In addition, gets the results of incidence variation resulted from the air - extraction, and gives a guide for further optimization and design of the stages.
