Vortex bladeless turbine is a non-conventional turbine that does not use any rotor blades to capture energy from flowing fluid. The device captures the energy of periodic vortices shed downstream of a bluff body, an aero- hydrodynamic effect that has plagued structural engineers and architects for ages in different engineering designs. As the wind passes a fixed structure, the Von Karman vortex sheet-type vortices generate alternate lift forces on the mast (movable structure) and make it start oscillating. Research has shown that such bladeless turbines have an excellent ability to harvest low-speed wind or hydro-energy. Innovative modifications of the mast’s outer surface open the possibility of extracting energy from a flowing stream. In this paper, a new mast system is designed, developed, and experimented with in an open airflow system, which results in a nearly fivefold increase in the amplitude of the vibrations due to vortices. Wake-Induced Vibration (WIV) is also tested in another set of experiments which does not show the same possibilities.

In present situation, India is one of the top growing economies. The various sectors contributing to this,need electricity for its functioning. Non-renewable resources being depleted day by day, importance is given to develop power from renewable sources of energy like wind, solar, hydro energy etc. In the year 2017-2018 the total utility power generated in India is 1,303,493 GWh and captive power generated is 183,000 GWh making a total of 1,486,493 GWh. Out of 1,303,493 GWh, 52,666 GWh(4% utility power) is generated using wind power. The aim of this project is to utilize wind power to its maximum potential to generate electricity. The region of high speed wind is limited and the area required for installation of conventional windmill is high due to the wake effect. Research is done to find new innovative methods that can operate under optimum wind conditions, under less area by minimizing wake effect and provide an efficient output. One such technology is Bladeless turbine that provides a quiet, safe, simple and efficient alternative to the conventional bladed turbines. Bladeless turbine is not actually a turbine, since it does not rotate. This new approach captures wind energy based on the phenomenon of aeroelastic resonance. Harnessing energy from the vortexes, a process called vortex shedding or Vortex Street. This causes the device to oscillate with little movement which is perfect to be placed anywhere without lubricants and without disturbing wildlife. Aeroelastic resonance phenomenon is usually considered as a problem but this has been used as basic technology for power major advantage of this turbine is that it has less moving parts, thereby reducing losses to a minimum. This is a new age turbine with improved performance that is economic, ecofriendly and less complex generation. Bladeless turbines are also the only ones with almost no harmful effects on the environment. Another with wear prone transmission being eliminated.

Vortex bladeless turbine antiquates the conventional wind turbine and adopts a radically innovative and novel approach to captivate the moving wind energy. This device effectively captures the energy of vorticity, an aerodynamic instability condition. As the wind passes a structure, the flow steers and cyclical patterns of vortices are generated.
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 ...
Vortex bladeless is a vortex induced vibration resonant power generator. It harnesses wind energy from a phenomenon of vorticity, called vortex shedding effect. Clearly bladeless technology consists of a cylinder fixed vertically on an elastic rod, instead of tower, nacelle and blades which are the crucial parts of a conventional wind turbine.
This study presents a comprehensive exploration centred on the morphology and surface structure of bladeless wind turbines (BWTs) aimed at optimizing their wind energy harvesting capability. Unlike conventional wind technology where vortex-induced vibration (VIV) is seen as problematic due to aeroelastic resonance, this effect becomes advantageous in BWT energy harvesters, devoid of frictional ...
