【摘要】 为了提升高负荷轴流压气机1维模型的计算精度，开展了基于负荷系数0.5的高负荷单级轴流压气机试验数据的1维模型校核，并运用校核后的1维模型对高负荷单级压气机设计特征进行了分析，探究其极限负荷水平。结果表明：在众多的1维模型中落后角、损失、分离流量模型对压气机总性能影响较大，选择以上3种模型进行校核即可达到工程设计所需的精度要求；采用常规负荷1维模型计算高负荷压气机性能的精度低于3维Numeca仿真的精度，主要体现在计算的落后角偏小、损失偏大、喘振裕度偏低；对于负荷系数0.5的高负荷单级轴流压气机，在1.00转速下的压比裕度低，喘振裕度主要依靠流量裕度提供，其叶片的最大气动负荷出现在转子上，能够稳定扩压最小de Haller数为0.506。更多还原

【Abstract】 To improve the prediction accuracy of one-dimensional(1D) models for highly loaded axial compressors and further investigate the design characteristics of highly loaded compressors, a 1D model was calibrated using experimental data from a highly loaded single-stage axial compressor with a loading coefficient of 0.5. The calibrated 1D model was then employed to analyze the design features of the highly loaded single-stage compressor and explore its ultimate loading level. The results indicate that among the numerous 1D models, the deviation angle, loss, and stall flow models have significant effects on the overall compressor performance. Calibrating these three models is sufficient to achieve the accuracy required for engineer-ing design. For highly loaded compressor simulations, the accuracy of conventional loading 1D models is lower than that of 3D Numeca simulations, which is manifested in underestimated deviation angle, overestimated loss, and underestimated surge margin. For highly loaded single-stage axial compressor with a loading coefficient of 0.5, the pressure ratio margin is low at 100% corrected speed, and the compressor surge margin mainly relies on the flow margin. The maximum aerody-namic loading occurs on the rotor, and the minimum de Haller number for stable diffusion is 0.506.更多还原
