摘　　要：以缩尺模化后的某大功率压气机前两级轴流压气机为对象,采用试验及数值的方法对进口可转导叶无角度变化和变角度下的压气机特性进行了对比研究,通过激光多普勒测速(Laser Doppler Velocimetery,LDV)系统对两级压气机第1级动叶进、出口的绝对气流角和绝对气流速度进行测量并与数值结果进行了对比分析。结果表明:试验与数值结果吻合较好,验证了数值方法的准确性;数值计算获得的压气机效率略高于试验结果;两级压气机缩尺模化前、后的压气机特性具有很高的相似性,流场具有基本相同的分布规律;缩尺模化后的两级压气机效率下降了1.23%。A comparative study was conducted on the characteristics of a two-stage axial flow compressor,using experimental and numerical methods under fixed and variable inlet guide vane conditions.The two-stage compressor was scaled and modeled from a high-power axial compressor.The absolute flow angle and velocity distributions in the spanwise direction at the inlet and the outlet of first rotor blade of the two-stage compressor were measured using a laser Doppler velocimetery(LDV)system.The calculated results are in good agreement with the measured results,verifying the correctness of numerical method.The calculated compressor efficiency is slightly higher than the experimental results.The characteristics of the two-stage compressors have a great similarity,and the flow fields of the two-stage compressor have the same distribution pattern before and after scaling and modeling.After scaling and modeling,the efficiency of the two-stage compressor decreases by 1.23%.
