Design and Analysis of Vortex Bladeless Windmill for Composite Material

Mr. Onkar D Kshirsagar, Mr. Amol B. Gaikwad


Nowadays, the non-renewable energy sources are gone to depth of the earth, so we obviously need to produce energy by using renewable energy sources. The traditional blade wind turbines are used to produce energy but its cost is very high and it have many disadvantages like as capital cost, maintenance cost, running cost, friction loss and it is also dangerous to birds and is noisy as well. Hence, there is a need to find low-priced and safe replacement to conventional windmills. The concept of bladeless windmill works on the theory of vortex shedding effect. Vortex bladeless windmills are a wind powered generator that generates electricity with minimum moving parts. It generates the electric current by using the oscillation or vibrations produced due to the wind. It’s working principle of vortex-induced vibrations (VIV). Hence, the electricity is generated by using linear alternator or piezoelectric material. Generally, structures are designed to minimize vortex-induced vibrations (VIV) in order to minimize mechanical failures. But in this project work, we try to increase the vortex-induced vibrations (VIV) with maximum deflection of bladeless windmills which is used to produce electricity with experimental and geometrical approach.
