摘　　要：对平板型喷嘴叶栅进行了试验研究,得到了4种不同来流条件下喷嘴叶栅的转矩变化规律,并对试验中的误差来源和误差水平进行了分析。通过试验对数值计算进行了验证。结果表明,数值计算结果与试验结果吻合良好,验证了采用数值计算方法进行喷嘴叶栅转矩预测的可行性。By the test of flat-plate cascade, the torque laws of nozzle cascade were acquired under four kinds of different flow. Based on this, the source and level of error were analyzed. Finally, the numerical calculation was testified. The results show that the calculated results have a coincidence with the experimental results, which verifies the feasibility of calculating the cascade torque with numerical method.
