Over the past few years in the generation of electricity from wind in new technological approaches, the generation of electricity from wind has been strong and positive interest which is able to be profitable at small scale. Vortex wind turbine could be also defined as to grow in advance, a totally new concept of wind turbine with different or traditional way which means without blades. In the bladeless wind turbine (BWT), there structure is a flexible cylindrical structure over the set up that extracts possible form of energy from moving airstream and utilizing such type of vortex induced vibration (VIV) method to induce the vibration in the structure. It is not only aerodynamic type of forces which could results in structural vibration during operation. The VIV method in which a blades are eliminated in such a way that structure will be having a long cylinder which is arranged on a flexible structure and placed in open environment where there will be moving air at certain velocity ‘air flow field’. The vibration is converted into electrical energy and the electrical energy utilizing a power unit, which is a power generation system i.e., piezoelectric generator arrangement. The result analysis is based on flow induced vibration which is characterized by poor conversion efficiency. The system is consider to be portable for experimentation hence the manufacturing parts is used as light in weight such as sheet, coil, piezoelectric arrangement and etc. It results in low investment and manufacturing cost. Experimental result and analytical data with appropriate conclusion is presented herewith through the present investigation. Results are highlighted based on the phenomenon of induced vibration at even critically low wind speed where traditional and conventional wind turbines may not yield required results.
