Abstract

Piezoelectric energy harvester (PEH) from wind energy is promising to provide long-term electric power for ecological environment monitoring sensors. In order to improve the output efficiency of piezoelectric power generation, vortex-induced vibration (VIV) is used to transform laminar airflow into high-frequency vibration. The ANSYS CFD numerical simulation model is established to analyze the wake flow field of VIV and PEH devices. Several monitoring points of flow field excitation characteristics were set up to analyze the air pressure generated by vortex street shedding from the wake region downstream of the blunt body. Meanwhile, the output characteristics of piezoelectric vibration excited by fluctuating pressure were simulated. Three kinds of bluff body shapes were used to evaluate vortex shedding strength in the wake area with the various wind speeds. The air pressure is discussed to explore the optimum area for energy harvesting. The airflow vortex-induced PVDF（Polyvinylidene fluoride）piezoelectric film deforms to generate electric power. The results show that the vibration intensity varies greatly in the wake region. Furthermore, it is higher with the triangular bluff body. The vortex-induced vibration frequency increases with the increase of wind speed. Meanwhile, the piezoelectric generation power is improved significantly.
