Hybrid wind energy scavenging by coupling vortex-induced vibrations and galloping - ScienceDirect
Source: sciencedirect.com
Article summary:
1. This paper presents a hybrid piezoelectric wind energy scavenger with different cross-sectioned bluff bodies, to enhance the energy scavenging performance by coupling both the vortex-induced vibrations (VIV) and galloping phenomena.
2. Aerodynamic coefficients for the distinct bluff-body cross-sections and attack angles can significantly affect the energy scavenger performance.
3. Computational fluid dynamics (CFD) studies are performed to interpret the observed performance improvement of the proposed hybrid energy scavenger.
Article analysis:
