Design and Construction of Vertical Axis Wind Turbine Blades

Abstract

This study aims to check the Vertical Axis Wind Turbines blades and their different types and their feasibility. Increase in energy demand results in need of clean energy like wind energy. This project is done to design and construct the vertical axis wind turbine blade for small scale usage. The vertical axis wind turbine is having axis of rotation vertically and that’s why yaw motor is eliminated. The demand of renwable energy sources is increasing day by day as the fossil fuel is limited and will end one day as well as it has adverse effect in environment and which leads to green house effect, etc

Introduction

I. INTRODUCTION

Fossil fuel is the main contributor of the adverse effect of environment and oil and gas reserves are finite, so world is looking for sustainable alternative energy source for the global energy demand. [1].

Wind energy is the most prominent option for the power generation in recent time and for commercial use . Since the researches is done majorly on horizontal axis wind turbine because it has large power output and greater efficiency as compared to vertical axis wind turbine. But vertical axis wind turbine have number of advantages against horizontal axis wind turbine.

Vertical axis wind turbine can be used for small scale and it can be installed in every building.

The installed wind potential of the world according to world wind energy association  is given in the graph.

II. TYPES OF WIND TURBINE

The Vertical axis wind turbine  have  two different types of set ups,  Darrieus and Savonius. Savonius type having half cylindrical blades generating drag difference  and  Darrieus type uses airfoil shape blades which creates pressure difference which generates lift force, which turns the main shaft and power is generates.[2].

III. BENEFITS OF VAWT

The vertical  axis  wind turbine runs in all direction but horizontal  axis wind turbine is uni-directional. Demerit of vertical axis wind turbine is it has lower efficiency but to overcome it cluasturing is done.[3].

Vertical axis wind turbine do not require any yaw motor arrangement but we require in horizontal axis wind turbine.

IV. DESIGNED VERTICAL AXIS WIND TURBINE

The blade of the designed vertical axis wind turbine is taken to be 10 inches wide and the height of the blade is 31 inches.

All five blades are attached over a shaft which rotates and delivers the power to the dynamo, this dynamo generates the power.

An experimental modal is being created of darrieus type and being investigated the results are obtained.  The turbine test is satisfactory and output voltage (12v max) is obtained and the charge is stored in a battery setup and after invertor the result is obtained and the capacity is 100 watts.

V. FUTURE WORK

Current study of planetary turbine is undergoing process and the the efficiencies of the turbine can be increased.

Conclusion

Today maximum machines are designed for reducing greenhouse emission which is cause of climate change. The dominance of non-renewable sources of energy is being reduced. The renewable source of energy provide clean energy by innovative ideas in technology. It not only deduce the electricity bill but also reduces the adverse effect of pollution on environment and also reduces effect on ozone layer. The vertical axis wind turbine is only used for small power output and is designed to meet environmental pollution . So the wind turbine is used to minimize the dependency over the non-renewable sources of energy.
