| 摘 要： | 对不同轴向间距下的某跨声速轴流压气机内流场在设计转速时进行了定常数值模拟,结果表明当转子与上游静子轴向间距减小时,压气机的效率和压比有明显降低,而转子和下游静子间距减小时,压气机的效率和压比反而有所提高.进一步的非定常数值模拟结果表明:①转子与上游静子轴向间距减小时,转子前激波与静子尾缘干扰增强,造成了效率和压比的下降...

| Abstract: | The steady flow field of a transonic axial compressor under design rotation speed was numerically simulated,proving that the close spacing between upstream stator and rotor can largely reduce the efficiency and pressure ratio,however the close spacing between rotor and downstream stator can improve the efficiency and pressure ratio.The unsteady numerical simulation indicates:(1) the close spacing between upstream stator and rotor can enlarge the interaction of rotor shock on the stator wake,causing the dete... |
