设计点总对总效率ηtt=0.8912,总对静效率ηts=0.6413,静对静效率ηss=0.7737,满足系统设计时的要求。但可以看出压气机的整体性能偏低,设计点靠近喘振点,叶轮需要进一步优化改进。
the total efficiency is ηtt = 0.8912, the total static efficiency is ηts = 0.6413, and the static efficiency is ηss = 0.7737, which meets the requirements of the system design. However, it can be seen that the overall performance of the compressor is low, the design point is close to the surge point, and the impeller needs further optimization and improvement.
