A State-of-the-Art Review on Vortex Induced Vibrations Phenomenon Bladeless Wind Turbine Technology

Abstract

Vortex bladeless wind turbine (VBWT) is a new wind power extraction technology that is dependent on the Aero-elasticity phenomenon that is called vortex induced vibrations – VIV – which is derived from the study of flow induced vibrations, it is the phenomenon that arises from the interaction of inertial, structural and aerodynamic forces over a bluff body. it has been found that when Air – ideal gas - flows around a body an induced oscillatory motion can be established by vortex shedding. By leveraging the induced oscillatory motion resulting from VIV, Vortex Bladeless aims to generate power in a novel way. The absence of traditional blades sets this technology apart from conventional wind turbines and introduces different dynamics in the extraction of wind energy. VBWT devices are particularly advantageous in low to moderate wind situations, where traditional turbines may prove inefficient or unfeasible. Moreover, their reduced noise levels and compact size render them suitable for urban or ecologically sensitive regions. The selection of this new technology to be investigated and studied will play an important role in wind energy field of study opening a new chapter in the development of this kind of renewable energy, leading to generate power with a lesser cost than that produced by the conventional wind turbines by 40 %. Nonetheless, the efficacy of VBWT may be constrained in high-wind conditions where conventional turbines thrive, and their performance is significantly influenced by certain design and resonance attributes.
