Design and Development of Building Augmented Wind-Turbine

Abstract

Energy demand is growing day by day due to the more industrialization in the world. The per- vasiveness of wind, low production cost and much progress within the field, the wind power offers a huge and assuring renewable energy resource. Integration of small wind turbines and its hybrid applications can plays an increasingly important role in a future distribution network. It is dif- _cult to extract a maximum amount of kinetic energy from the wind in the built environment. Mostly all the wind source developed in the obstacle-free area. It is necessary to utilize the natural wind source and developed a system to provide a solution of energy to the humankind from the built environment. There are different types of wind turbine system that are in use today where turbines are accumulated on the side or rooftop of a building. The purpose of this project is to build up advanced knowledge, incorporated solutions and technologies of wind turbines for the built environment. Building augmented wind turbine (BAWT) is an innovative propose that the wind-turbine attached between the building's vacant area in which building structure helps to increase the wind flow for the rotor. This study concentrates on wind-turbine with buildings are acting as a wind concentrator and to determine the increase of power that can be achieved using building facades as augmenters. The essence of the location is very significant for different types of turbine for the increment of wind velocity and power generation. The Savonius VAWT is used because it requires low wind speed for the rotation, independent of the wind direction and low built-up cost. This study used computational fluid dynamic models to analyze wind-turbine in building-geometry and its impression on power growth. The BAWT and free standing wind turbine is compared based on the power growth.
