2.
Mixed flow compressor achieves better performance and lower tip leakage loss,and flow field at outlet is more uniform in mixed flow impeller than centrifugal impeller.
计算结果表明在高比转速情况下,斜流叶轮有利于减弱叶尖泄漏损失,改善叶轮出口均匀性,提高叶轮效率和级效率。
3.
The results show that increasing hub design circulation could make impeller achieve better performance and lower tip leakage loss,and make flow field at outlet more uniform,but increasing tip design circulation could make impeller achieve higher ratio of total pressure in surge condition.
以高负荷高比转速斜流叶轮为例,采用数值模拟的方法,在级环境下分析了斜流叶轮根尖加功量分配形式对于斜流叶轮总体性能、叶尖泄漏以及出口均匀性的影响,讨论了斜流叶轮根尖加功量分配影响的内在机制。
