Abstract
Small-scale vertical axis wind turbine (VAWT) rotor is developed for use in areas lacking adequate energy infrastructure. The materials and methods of construction are selected to minimize cost as much as possible. The paper describes the design of different kinds of vertical axis wind turbine rotors having different number of blades and twist angle. The aim of the work is to study the influence of the different designs on rotational speed and power of rotor in different wind speed.
Highlights
The rising cost of fossil fuel and effects of climate change forces to enhance the demand of renewable energy sources in different sector
Like as other renewable energy sources, wind power has a key role in reducing greenhouse gas emissions [1]
Different types of blade is developed and placed in wind tunnel, where, rotational speed is measured in variation of wind speeds
Summary
The rising cost of fossil fuel and effects of climate change forces to enhance the demand of renewable energy sources in different sector. A wind turbine is a device that taps the renewable kinetic energy of blowing wind, which converts it to useable mechanical, electrical or thermal energy. The function of a wind electric generator is to convert the kinetic energy of the wind into most useful form of energy i.e. electricity. The basic design requires the conversion done in the most efficient way and at lowest cost. This is done in few steps such as kinetic energy of the wind, converted through blades to mechanical energy of a rotating shaft and transmitted through a gearbox to a generator, which converts the
