| 摘 要： | 对常规直叶片、正弯曲叶片及反弯曲叶片组成的３种平面扩压叶栅的叶片表面静压和出口流场在－５°，０°，５°及１０°四个攻角下进行了测量，并给出了叶片表面静压分布特性及出口流场的能量损失分布特性。本文试图从叶片表面静压分布来分析弯曲扩压叶栅的能量损失机理，探讨不同弯曲叶片在扩压叶栅中应用的变工况性能。

| Abstract: | The exit flow field and the static pressure on the blade surface for three sets of different cascades were measured at four incidences of -5°,0°,5° and 10° respectively in a low-speed cascade wind tunnel.The three sets were a conventional straight cascade,a positive curved one and a negative curved one.The static pressure distributions on blade surfaces and the energy loss distribution in the exit flow fields have been obtained.The purpose of this paper is to find out the energy loss mechanism of the curved blade cascades from the static pressure distribution on the blade surface,and to study performance of compressor cascades at different incidences. |
