| 摘 要： | 以NASA Rotor35为研究对象,应用数值模拟方法深入研究了叶表抽吸和端壁抽吸的不同抽吸组合布局对该跨音速压气机流场结构以及其性能影响规律.研究结果表明:四种抽吸组合在不同的抽吸量下均使压气机的压比和效率有所提高,相对叶表抽吸或端壁抽吸,其在较大的抽吸量时对压气机性能的提升较大,在抽吸量Sc=2.0%时最佳抽吸组合...

| Abstract: | The NASA Rotor35 with boundary layer suction(BLS) at blade suction surface and end-wall is investigated by numerical simulation to explore a better combination suction distribution to control the flow structure and performance of this transonic compressor rotor.The results show that: The performance of compressor is improved by the four combination suction with vary suction flow rate.Compared with the blade surface suction and end-wall suction,combination suction can obtain larger positive effect at higher ... |
