Numerical study on the flow and noise control mechanism of wavy cylinder

Binnian Chen et al.

Summary: This study investigates the ability of a wavy cylinder in improving aerodynamic performance and reducing aerodynamic noise. The results show that the wavy cylinder helps reduce drag coefficient and suppress fluctuation of lift coefficient, leading to overall noise reduction. Furthermore, the reduction in vorticity generation near the wavy cylinder wall and the suppression of periodic vortex shedding contribute significantly to the noise reduction. The findings highlight the close relationship between drag reduction and noise suppression in the wavy cylinder.

Fluid-structure-sound interaction in noise reduction of a circular cylinder with flexible splitter plate

Fan Duan et al.

Summary: The study investigates the impact of fluid-structure-sound interaction on flow-induced noise reduction by attaching splitter plates to the rear of a circular cylinder. The experiment shows that flexible splitter plates can effectively reduce Aeolian tone under certain parameters, with their movement pattern having significant effects on secondary and high-frequency noise.
