Modal and Static Analysis of Vortex Bladeless Wind Turbines with Different Geometries

Abstract

The renewable energy industry has undergone remarkable growth in recent times, with wind energy assuming a preeminent role as a source of clean energy. Five distinctive geometries were analyzed, including a traditional circular form, a decagonal form, and three sinusoidal forms to evaluate the modal and structural characteristics of vortex bladeless wind turbines. The ANSYS software was employed to carry out both the modal and structural analysis. The vortex bladeless rod was firmly fixed and the mast was exposed to a wind pressure of 15 Pa during modal analysis. The structural analysis was executed to compute the deflection of the vortex bladeless wind turbine under the same wind pressure. The results demonstrated that the sinusoidal forms exhibited the greatest deflection at a wind speed of 5m/s. These findings possess the potential to optimize and augment the design of vortex bladeless wind turbines, provide guidance for future design decisions, and boost the efficiency and dependability of these wind turbines. It is therefore posited that the consideration of diverse geometries in the design of vortex bladeless wind turbines is of paramount importance, and the findings of this study are expected to be of great use to engineers and designers in the wind energy field, thereby catalyzing the progression of this thriving renewable energy source.
