Abstract

This paper presents a continue research work of last year which introduced a first experimental research work [1]. Compared with previous work, the difference of this research is that the effects of the different stator angles with blowing and without blowing are studied. In this research the pressure of blowing flow is stable at 0.8MPa. The flow rate is 6.0 m3/h which is about 0.4998% of total mass flow. After angles of one stator or two are separately adjusted, acoustic characteristics and flow fields are calculated and measured, the results are analysed. The experimental results show that the trailing edge blowing technology can effectively reduce the sound pressure level (SPL) of stator/rotor interaction noise in the compressor by compensating the axial pressure loss. The stator angle can make maximum order changed. The noise of 2BPF could be reduced above 7dB.
