| 摘 要： | 扩压器处于超临界工作状态时,由于喉道后面的激波与附面层的相互作用,使出口流场发生畸变.本文探讨了扩压器内发生的冷凝对畸交流场的影响.结果表明,在实验范围内,由于冷凝使畸变流场的平均紊流度增加12～25%,稳态畸变指数DC_(60)可能增加、不变或减小.可见在研究发动机与进气道的相容性时,冷凝是不可忽视的影响因素之一.

| Abstract: | Condensation is possible when the ambient humidity and Mach number of the air flow in the inlet are both sufficiently high. The condensation leads the average turbulence to be increased by 12-25% and the steady-state distortion factor, DC60, to be changed obviously in the experimental range. The condensation effect on the distortion flow field should be considered in the study of tolerability between engine and inlet. |
