摘　　要：采用商用软件NUMECA数值模拟了大尺度扇形叶栅内的流动状况。通过将计算结果与低速风洞实验研究测量得到的超临界汽轮机调节级导叶原型叶栅的试验数据进行对比研究,认为应用NUMECA商用软件计算叶栅绕流既能够定性地又能近似定量地反映实际流动状况。The commercial software NUMECA was applied on numerical simulating the flow situation in the large scale section cascades in the present paper. By comparing the calculation results with the test results that were measured in, the low speed wind tunnel of the original super-critical guide vane cascade. The present paper thinks that using the commercial software NUMECA to calculate the cascade flow can not only qualitatively but also almost quantificationally reflect the real flow situation.
