Abstract
Today, only a small fraction of the world's electricity is generated by wind, however, demand for this renewable energy resource will continue to increase with the depletion of fossil fuels. Fast-response porous polymer paint was selected for the blade coating. This paint is a polymer/ceramic based PSP, which was designed specifically to improve the diffusivity of the binder material, thus allowing faster response times. Its kinetic characteristics were good and its response time can be as fast as 3.6 kHz, which is sufficient to study the flow field on airfoils with oscillating free stream frequencies less than 20Hz.A wind turbine is a type of turbo machine that transfers fluid energy to mechanical energy through the use of blades and a shaft and converts that form of energy to electricity through the use of a generator. Depending on whether the flow is parallel to the axis of rotation (axial flow) or perpendicular (radial flow), determines the classification of the wind turbine. Each type of wind turbine has its strengths and weaknesses, but in the end, all wind turbines accomplish the same task. With mounting global pressure for sustainable energy technologies, there is a growing need to restructure traditional wind, solar and geothermal technologies to increase deployment over a greater range of conditions. Although efficient under open conditions, Traditional horizontal axis wind turbines (HAWTs) are not optimal for use in dense urban settings where wind speed and direction are more variable. Conversely, vertical axis wind turbines (VAWTs) can take advantage of incoming wind from any angle, and typically perform better at lower wind speeds associated with the topography of existing infrastructure. A new hybrid blade, blending Darrieus and Savonius qualities, has been investigated using numerical and computational fluid dynamics methods. There are other people that are connected to the grid but still have energy cuts. For these people, it seems to be cheaper to have a grid connection than to have an independent energy source, reasons for that are that in an isolated installation the energy has to be chemically stored in batteries, with limited lifetime that makes renewal costs comparable to those of a grid connection. Furthermore, there are places which will not have electricity access, these places coincide with the poorest and isolated rural areas of developing countries, and these people cannot afford the cost of a wind turbine, nor small nor bigger. Maybe a free turbine design, that anyone with common workshop materials could build, would make a difference in the living conditions of this people. The purpose of this paper is to provide an alternative to these people. Finally, the structural behaviour of the turbine is analysed. © 2017 IAEME Publication.
