均匀来流下叶片吸力面附面层特性的实验研究的中期报告摘要：本文介绍了一项针对均匀来流下叶片吸力面附面层特性的实验研究的中期报告。试验采用了Pitot管、全电子测速仪等测量仪器，对不同来流速度下叶片吸力面流场特性进行研究。结果表明，随着来流速度的增加，叶片吸力面上的局部负压区域显著增大，同时流动的湍流强度也有所增加。同时，通过计算得出了不同实验条件下的Reynolds数，发现实验条件与理论计算预测结果相符合。关键词：来流速度；附面层；流场特性；Pitot管；全电子测速仪Abstract:Thispaperpresentsamid-termreportonanexperimentalstudyofthecharacteristicsoftheboundarylayeronthesuctionsurfaceofabladeunderuniforminflow.TheexperimentusedmeasuringinstrumentssuchasPitottubeandanelectronflowmetertoinvestigatetheflowcharacteristicsofthesuctionsideofthebladeunderdifferentinflowvelocities.Theresultsshowthatwiththeincreaseofinflowvelocity,thelocalnegativepressureareaonthesuctionsurfaceofthebladesignificantlyincreases,andtheturbulenceintensityoftheflowalsoincreases.Atthesametime,theReynoldsnumberunderdifferentexperimentalconditionswascalculated,anditwasfoundthattheexperimentalconditionswereinagreementwiththetheoreticalcalculationpredictions.Keywords:inflowvelocity;boundarylayer;flowcharacteristics;Pitottube;electronflowmeter.
