Abstract
En 中文
The growing demand for sustainable energy has driven research into innovative wind energy harvesting technologies. Vortex bladeless wind turbines (BWTs) present a promising alternative to conventional turbines, offering reduced mechanical complexity, improved reliability, and suitability for micro-grid and urban applications. Recent studies have explored resonance-tuned masts, linear generators, and piezoelectric transducers, but challenges remain in achieving high voltage output, wide operational range, and experimental validation of grid-connected systems. This paper presents a bladeless wind turbine prototype integrating a resonance-tuned mast with a linear generator and DC-DC boost converter, designed to maximize energy extraction under varying wind conditions. The system is evaluated experimentally under both on-grid and off-grid conditions, and results are corroborated with COMSOL Multiphysics and MATLAB simulations. The proposed design demonstrates enhanced energy conversion efficiency, improved voltage output, and practical scalability, addressing key limitations of previous BWT studies and advancing the field toward urban and micro-grid deployment. Experimental findings demonstrate agreement with theoretical predictions.
