在低速平面叶栅风洞中对4种具有不同几何尺寸流向微槽的非光滑叶片叶栅进行了实验研究,主要研究非光滑叶片对叶栅出口能量损失系数的影响。实验结果表明,采用非光滑叶片可以减少叶栅损失,相对减少最多16.5%,最少9.1%。
In the low-speed plane cascade wind tunnel, four kinds of non-smooth blade cascades with different geometry flow to the microgrooves are experimentally studied, and the influence of the non-smooth blade on the energy loss coefficient of the cascade exit is mainly studied. Experimental results show that the use of non-smooth blades can reduce the cascade losses, a relative reduction of up to 16.5%, at least 9.1%.
