摘要：

In order to improve the matching accuracy between the compressor and the turbocharger under the unsteady flow condition,the internal joint operation law method was proposed based on the turbocharger operating conditions, and the unsteady flow characteristics of the compressor with different structures and performance correction were studied. The results shows that among the three structures of compressors, except for the high speed and high flow rate joint point operation condition,the unsteady flow performance of the equal-length blade compressor with a 1 mm reduction in inlet diameter has obvious advantages and a better surge performance. After the correction of compressor performance based on the unsteady coefficient, the performance of the compressor was closer to the real working condition. © 2024 Science Press.
