| Abstract: | The mixed flow field and noise characteristic of the stator wake interaction with rotor with/without injection through a slit along the stator's rear end was investigated using noise measurement equipments and particle image velocimetry.In the velocity fields,the spreading characteristics of the wakes across the rotor row were gained.The interaction flow field between pure wake and rotor was compared with the flow field between weak wake,momentumless wake,jet and rotors.The results show that the momentumles... |
| Keywords: | trailing edge blowing wake momentumless wake PIV(particle image velocimetry) stator-rotor interaction flow field measurement |
