Abstract Three stators with different lean angle were employed for numerical study to obtain the rotor’s wake evolution, and to get the RMS pressure and ΔCp at stators’ surface. At the experiment part, the noise spectra were measured to compare with numerical study. The results indicate that the wakes of rotor interaction with stator is the main source of noise, and the stator with different lean angle can change the phase of rotor’s wake, the first harmonic of tone noise is the reason for difference of the total sound pressure level (SPL).
