| 摘 要： | 采用数值模拟方法对燃气轮机跨声速涡轮级内动静叶的非定常气动干扰进行了深入的研究,分析了静叶尾迹输运、尾缘激波和尾迹涡的变化以及下游动叶静压的非定常扰动的影响。结果表明:燃气轮机跨音速涡轮级中静叶的非定常特定区域集中在吸力面扩压段到尾缘区域;尾缘激波的压力面分支在吸力面的反射激波对有下游动叶的影响非常大;尾迹传播方向随着下游势流的变化而产生相应的变化。

| Abstract: | Numerical method was carried out on the study of unsteady interference of transonic turbine stage's stator and rotor.The transport of stator's trailing wave,the change of trailing shock wave and the unsteady interrupt of rotor's surface pressure were all analyzed in detail.The result shows that stator's unsteady region concentrates from the diffusion section of the suction surface to the blade trailing;the reflect shock wave of trailing wave's pressure surface brench effects the flow field of downstream rot... |
