Abstract

Flow induced vibration generally exists in the field of engineering and nature. Due to the complexity and interdisciplinary, the flow induced vibration has always been one of the research hotspots in the academic community. The energy harvesting technology using passive turbulence control (PTC) to enhance flow induced vibration has attracted extensive attention. The study focused on the characteristics of flow induced vibration of cantilever vibrator by placing symmetrical square strip attachments with different angles on a smooth cylinder. The response of amplitude and frequency, output power and energy conversion efficiency, and the lift coefficient were obtained. The mechanism of passive turbulence control to enhance flow induced vibration was further revealed. The results showed that the maximum amplitude of PTC cylindrical vibrator is 2.0 D, which is 5 times that of smooth cylindrical vibrator; The maximum output power is 0.44 W, which is 14 times of the maximum output power of the smooth cylindrical vibrator. The reasonable placement angle of the attachment can make the vibration of the vibrator develop from vortex induced vibration to galloping, and obtain high output power and energy conversion efficiency, which provides necessary theoretical guidance and technical support for energy conversion and collection by flow induced vibration.
