Abstract: Vortex-induced vibrations (VIV) occur when fluctuating drag and lift forces caused by fluid-structure interactions lead to periodic oscillations. Historically considered an engineering challenge, recent advancements view VIV as an opportunity for energy harvesting. This paper presents the development and testing of a VIV-based hydro-kinetic energy harnessing system. Laboratory experiments conducted in a circulating channel at the Hydrodynamics Laboratory of IIT Kharagpur demonstrate the conversion of vortex-induced mechanical oscillations into electrical. Numerical simulations using OpenFOAM are also carried out to validate the experimental findings, offering insights into the vibrational responses of the system. This technology holds promise for sustainable low-power energy systems in natural fluid environments.
