文献[1]首先提出了采用倾斜叶片来降低透平静叶损失的设想。此后有过许多研究都表明,适当改变积叠方式可以改变叶片表面径向压力分布,以达到控制附面层内低能量流体的流动、减少叶栅损失的目的。为了了解这种措施对流场的影响,本文以文献[7]中用传统周期性条件的全三元势函数程序,对文献[3]中径高比为3的实验叶栅(图1和2)求出了径向叶栅、正倾斜20°、负倾斜20°及复合倾斜叶栅(根部正倾斜20°,顶部基本径向)内的全三元流场,并对计算结果进行了分析。 Literature [1] first proposed the use of inclined blades to reduce the loss of turbine stationary vane idea. Since then, many studies have shown that the appropriate change in stacking mode can change the radial pressure distribution on the blade surface in order to achieve the purpose of controlling the flow of low-energy fluid in the coating and reducing the loss of cascades. In order to understand the effect of this measure on the flow field, this paper uses the all-ternary potential function of the traditional periodic conditions in [7] to study the experimental cascade with the aspect ratio of 3 in [3] 2) The full cascade flow field of the radial cascades, 20 ° positive, 20 ° negative and the compound inclined cascade (the base is inclined at 20 ° and the basic radial direction at the top) is obtained. The calculation results analysis.
