轴流压气机计算机辅助试验研究
COMPUTER-AIDED EXPERIMENTAL INVESTIGATION OF AXIAL-FLOW COMPRESSORS
-
摘要: 压气机试验研究的重要目的是发现其内部工作不好的部位,为修改设计提供可靠的依据。由于实际测取参数的位置和数量有限,希望通过实测数据与计算机计算相结合进行详尽的气动分析,从而能够对整个流场作出仔细的判断。Abstract: An approach has been developed to evaluate some important aerodynamic parameterssuch as air-flow angle, blockage factor and loss coefficient, at immeasurablesurfaces. It can be used for two cases of measurement of multi-stage, axial-flow compressors. In order to testify this approach, several examples have been calculated and the results show that this approach provides reliable data for further performance improvement.
