Noise reduction and efficiency enhancement are the two important directions in the development of the multiblade centrifugal fan. In this study. we attempt to develop a bionic airfoil based on the owl wing and investigate its aerodynamic performance and noise-reduction mechanism at the relatively low Reynolds number.
