EFFECTS OF AXIAL VELOCITY DENSITY RATIO ON CASCADE PERFORMANCES
-
摘要: 轴向密流比对叶栅性能有较大的影响,本文对该问题进行理论及实验研究,导出了叶栅主要性能参数与轴向密流比的关联方程,通过压气机叶栅吹风实验,得到了不同轴向密流比条件下的叶栅性能。理论计算与实验结果吻合的程度令人满意,表明文中所得出的理论关联式可以有效地估算轴向密流比对叶栅流动的影响,具有一定的实用价值。Abstract: In turbomachinary cascade flows, the effects of Axial Velocity Density Ratio (AVDR) on cascade performances are very important. The theoretical and experiment of the problem are presented in this paper. The theoretical correlations of mafor cascade mances with AVDR are obtained. The comparisons of calculations and exper s are ir good agreemens
