Abstract:

<strong><strong> </strong>It uses a radically new approach to capturing wind energy. The device captures the energy of vortices,an aerodynamic effect that has plagued structural engineers and architects for ages (vortex shedding effect). As the wind bypasses a fixed structure,its flow changes and generates a cyclical pattern of vortices. Once these forces are strong enough,the fixed structure starts oscillating,may enter into resonance with the lateral forces of the wind,and even collapse. There is a classic academic example of the Tacoma Narrows Bridge,which collapsed three months after

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 ex

The idea of bladeless windmills is based on the vortex shedding effect hypothesis. A wind-powered generator with the fewest moving elements is the vortex bladeless windmill. The oscillation or vibration caused by the wind is used to generate the electric current. As a result, piezoelectric material or a linear alternator are used to generate electricity. In this project effort, we attempted to increase the vortex-induced vibrations of the turbine built of Epoxy Carbon UD (230GPa) by altering the design of the mast and base.

This paper investigates the dynamics of an electromagnetic vortex bladeless wind turbine (VBWT) with a tunable mechanism. The tunable mechanism comprises a progressive-rate spring that is attached to an oscillating magnet inside an electromagnetic coil. The spring stiffness is progressively adjusted as the wind speed changes to tune the turbine fundamental frequency to match the shedding frequency of the vortex-induced vibration (VIV) due to the wind flow crossing over the oscillating mast.

A bladeless wind turbine utilizes vortex formation to extract energy from the wind. Vortex formation are small swirls of air which occur as a result of the geometric shape of the device. This study designed a bladeless wind turbine which incorporates a structural support at a distance offset from the center axis of the cylindrical mast. Springs were added to the final design as means to provide the stiffness required to obtain resonance with the vortex shedding frequency and to also assist in supporting the structure. The analysis was conducted at wind speeds 1m/s, 4m/s and 7m/s, where the geo

Abstract:

The increasing demand for efficient and sustainable wind energy solutions has led to the development of vortex bladeless wind turbines (VBWTs), which utilize nonrotary masts and electromechanical components to harness wind energy through vortex‐induced vibrations. Despite their potential, the aerodynamic performance of VBWTs remains limited by the mast’s geometry, presenting a critical research gap. This study investigates the impact of introducing shallow hexagonal dimples on the mast surface to enhance turbine performance. CAD models were developed with six dimple columns strategically place

Abstract:

The use of bladeless wind turbines (BWTs) for power generation has grown, but their performance under various environmental conditions, particularly dust accumulation, requires further study. This research develops a theoretical mathematical model based on continuity, momentum, and vortex equations to analyze the vibration behavior of the BWT mast, focusing on vortex-induced vibrations. Numerical simulations explore the relationships between dusty wind velocity, vortex shedding frequency, elasticity constant, converted power, and efficiency. The effects of mast height and diameter on oscillati

Abstract:

Wind energy is recognized not only for its high generating capacity among renewable sources, but also for its growing popularity in recent years. However, conventional wind turbines, which rely on blades to capture wind energy, present significant challenges, including noise pollution, interference with bird migration and the frequent need for maintenance due to the complexity of their mechanical components. In an attempt to minimize these problems, current innovations include bladeless wind turbines (VBWT). These operate from wind-induced vibrations, mostly vortex-induced vibrations (VIV). Am
