文摘

•: The effect of deviation angle of an abnormal blade on fan performance is examined.
•: Comparison of fan performance under different deviation angles is performed.
•: Aerodynamic noise is predicted using Large Eddy Simulation and FW–H noise model.
•: Wavelet packet and empirical mode decomposition are used to decompose sound pressure.
•: The energy features of sound pressure under different deviation angles are extracted.
