Abstract
Vortex bladeless turbines (VBTs), which extract energy from vortex-induced vibrations (VIV), represent a promising class of micro-wind generators characterized by low acoustic impact, simple mechanics, and minimal wake interactions. This review consolidates advances reported between 2018 and 2025, covering Strouhal-driven shedding mechanisms, nonlinear lock-in dynamics, and recent developments in CFD-FSI simulation and reduced-order modeling. The analysis formalizes aerodynamic forcing and resonance-based power extraction, emphasizing how geometry, damping, and effective mass govern the stability, bandwidth, and durability of the oscillatory response. Progress in materials engineering - such as high-modulus composites, hybrid piezoelectric–electromagnetic converters, and tunable-stiffness architectures - strengthens fatigue resistance under harsh desert or coastal climates.
Performance evaluation is synthesized using IEC-inspired indicators and compared with conventional small HAWT and VAWT technologies. Adaptive resonance-tracking concepts, including sliding-mass systems and semi-active stiffness modules, are reviewed for maintaining synchronization under transient wind inflows. Owing to their inherently weak wake, VBTs support compact arrays and AI-assisted optimization strategies. Finally, the review discusses how the nocturnal wind profile characteristic of arid regions enables VBTs to complement daytime photovoltaic production, supporting hybrid microgrids. Key research needs include endurance testing, standardized certification, and transparent LCOE frameworks for future multi-kilowatt VBT deployment.
