摘要

利用表面热膜测量上游尾迹周期性扫掠下某超高负荷低压涡轮叶片吸力面附面层的非定常流动特性.通过热膜测得的准壁面剪切力及其统计参数云图分析了尾迹与附面层的相互作用对分离、转捩及再附过程的影响.实验结果表明:对于低雷诺数Re超高负荷产生较大分离泡的情形

尾迹扫掠对涡轮叶片附面层的发展具有显著影响

能够有效地抑制附面层的流动分离.

Abstract

An experimental investigation on unsteady boundary layer behaviors of the suction surface of an ultra-high-lift low pressure turbine profile under periodically unsteady wakes was conducted with the help of surface-mounted hot film

and the influence of the wake-boundary layer interaction on the boundary layer separation

transition and reattachment was analyzed in detail with space-time (S-T) diagrams of quasi-wall shear stress and statistical parameters.The experimental results show that the wake has a significant influence on the boundary layer of turbine profile and the separation has been remarkably suppressed despite the larger separation bubble on the suction surface of ultra-high-lift profile at low Reynolds number.
