为了更加精确地测量附面层流动状态,并验证表面热膜测试技术的可靠性,利用表面热膜测量了低雷诺数定常来流条件下高负荷涡轮叶栅通道内叶片吸力面附面层的流动状态,并与表面静压实验测得结果进行对比。结果表明,利用表面热膜测得的准壁面剪切力以及相关的统计参数能够准确捕捉到附面层分离泡和转捩的位置,对于高负荷低压涡轮叶型附面层流动测量是可靠有效的。 In order to measure the flow state of the interface layer more accurately and verify the reliability of the surface thermal film testing technology, the surface thermal film was used to measure the surface layer of the suction surface of the blade in the high load turbine cascade under steady flow with low Reynolds number Flow conditions, and with the surface static pressure test results were compared. The results show that the quasi-wall shear force measured by the surface thermal film and the related statistical parameters can accurately capture the location of the separation bubbles and transitions in the laminates, which is reliable and valid for the measurement of laminar flow in high-load and low-pressure turbine blades of.
