摘要：

A more accurate calibration and measurement technique with a single wire velocity measuring instrument is used to study the unsteady velocity between the rotors of a counter-rotating axial fan, and some special concluding remarks of unsteady effects were obtained. The unsteady potential influence of the downstream rotor is a dominant factor; the wake disturbance of the upstream rotor is less important. The radial velocity is mainly affected by the vortex strength of the secondary flow at the upstream blade tip and hub region. These results are important for elucidating the mechanism of unsteady flow in a counter-rotating axial compressing system.
