Abstract: | Non-axisymmetric wake impact experiments were carried out after the best exciting frequency for a low speed axial compressor had been found by axisymmetric wake impact experiments.When the number and circumferential distribution of inlet guide vanes(IGV) are logical, the wakes of non-axisymmetric IGVs can exert beneficial unsteady exciting effect on their downstream rotor flow fields and improve the compressor's performance.In the present paper,four non-axisymmetric wake impact plans were found working bett... |
