Theoretical and numerical analysis of vortex bladeless wind turbines

Theoretical and numerical analysis of vortex bladeless wind turbines Wind energy is one of the most abundant renewable energy resources that have been used to generate electricity.

Abstract

Wind energy is one of the most abundant renewable energy resources that have been used to generate electricity. A new used method called Vortex Bladeless Wind Turbines which is basically a rod oscillating and vibrating in response to the vortices originating from the wind passing by the rod. This paper presents a mathematical model used in analysis the work of the VBWT. A prototype design was be created using solidwork to calculate the physical properties. In addition, a numerical study was carried out using Ansys software to calculate the forces affecting the VBWT. Finally, the safety of VBWT structure is studied. The results indicated that, the obtained model can be applied practically in studying the performance of general VBWT with low wind speed, as VBWT use less space, low maintenance and hence economical. The mathematical formula of VBWT power is function of air velocity, aerodynamic coefficients, and prototype physical properties.
