Abstract
The rapid urbanisation and power demand has initiated the need for utilisation of renewable energy technologies in day to day applications. With the wind resource assessment in India has revealed the potential of small and micro scale wind power and harnessing is going to contribute the countries vision of achieving 60 - 89 GW [GWEO-2012] wind power by 2020. Several urban and remote areas in the south and western parts of the country have pertinent locations with low power density of 150W/m2, the VAWT are seen as the viable source of tapping this particular range of energy density, for powering and storage especially in remote areas and aid in mitigation of carbon foot prints linked to the direct carbon emissions and also due to power generation by fossil fuels. The proposed and one of the widely adapted savonius type VAWTâs are inherent in harnessing this low and medium energy dense wind along with simpler construction compared to other wind turbines. The VAWT is compared analytically with the both the Radial and axial-flux for efficient operation and savonius wind turbine designed with low torque application using analytical and CFD. It is aimed for heating and drying applications thus reducing carbon emissions. The operation of the wind turbine for very lying and areas were the space constraints have also been considered for enabling easy installation and operation. This implication of using two types of flux machines enabled us to choose the efficient one at different zones of applications like roof top, types of wind zones I,II,III etc., this aids in greatly reducing the time to design different configuration at different locations and applications like poultry, core agricultural areas and other remote or standalone systems. The output of the type II machines are more applicable for high energy for less duration like instant heating and cutting applications.
