“…The rotational wind harvesting involves the traditional large-span blades that rotate and generate electricity at varying wind speeds, such as the traditional horizontal axis wind turbines, and the vertical axis wind turbine, which has been previously researched numerically by Pervaiz et al [13] to optimized it and to understand its performance under different conditions, but the fact remains that these two configurations require sufficient wind speeds to operate. However, oscillation wind harvesting has been studied for the past couple of years [14][15][16]. In this method, a small wind gust flowing over a body is disturbed by the body creating turbulence downstream.…”

This study combines experimental and numerical evaluations of Vortex Bladeless Wind Turbines (VBWTs) to understand their potential in renewable energy generation. The methodology employs Two-Way Fluid–Solid Interface (FSI) simulations, alongside real-world data, providing important insights into the turbine’s vibration dynamics and flow interactions during operation. Key findings include identifying optimal vibration frequencies and amplitudes that enhance energy harvesting and a clear advantage in power-generation estimations shown by one of the models used. The study reveals possible applications of VBWT in various settings like airport runways, highways, and buildings, indicating a promising avenue for incorporating such renewable-energy solutions. Discussions on the economic feasibility and environmental benefits of VBWT deployment are also presented, suggesting a need for further research and optimization in this area. A conceptual generator design and business model are introduced as part of a broader discussion on technology integration and energy storage. The research in this study encompasses experimental and numerical analysis, to achieve a broader understanding of the workings of a VBWT, realizing the feasibility of using such systems in lower-wind-speed conditions and upscaling to higher-wind-speed cases.
