摘要

为研究雷诺数效应对叶栅流动的影响

对某可控扩散叶型的平面叶栅流动进行数值模拟

计算在叶弦雷诺数分别为1×106

7.7×104

1.6×104

7.2×103和3.4×103条件下的不同攻角的流动情况

研究雷诺数对叶栅总压损失系数和攻角特性的影响。对叶栅性能和流场特性进行了分析

结果表明随着雷诺数的降低

叶栅流动的总压损失系数不断上升

低损失攻角范围逐步减小。

Abstract

In order to analyze the effect of low-Reynolds number on the performance of some controlled diffusion airfoils

calculations were performed under different Re No.of 1×106

7.7×104

1.6×104

7.2×103

3.4×103with different incidences respectively.The results of numerical simulation show that the total pressure loss coefficient increases with the decrease of Reynolds number.Under the condition of low Reynolds number

the incidence range of low loss becomes narrow.
