| 摘 要： | 为了研究透平叶栅大负攻角分离流动的性质,在平面叶栅风洞上对叶栅流道内部及出口半叶高处的流场作了细致的测量,并测得了相应叶高处的叶型表面静压分布。用流动显示方法确定了叶型压力面上的分离区,初步拟出了分离流流型,并用二维时间推进法计算了无分离及有分离时的流场,得到了与实测值较为吻合的叶型表面静压分布及其它流动参数的分布。

| Abstract: | Detailed measurements of the mid-span flow field within and behind passage and static pressure distribution on airfoil surfaces were made in a plane cascade wind tunnel to investigate the characteristics of the large negative incidence separated flow in turbine cascades. The separated region was determind and the separated flow model was proposed by means of flow visualization method. By virtue of 2-D time marching method the flow fields with and without separation were calculated. Good agreement is found between the experimental results and the static pressure and other flow parameters distributions obtained. |
