摘要
采用5孔探针、表面静压孔和墨迹显示技术,对2套具有不同载荷分布的后部加载涡轮叶栅内的三维流场进行了详细的测量分析。结果表明:优化载荷分布的叶栅和原叶栅相比,总流动损失明显降低。
By using 5 - hole spherical probes, surface static pressure holes and flow visualization techniques, the 3D flow fields are measured and analyzed in two turbine aft - loaded cascades with different load distributions in detail. The test results have shown that the flow losses of cascades with optimized load distribution are significantly reduced in comparison with the original cascade.
