Abstract:
Analysis of a vertical axis wind rotor using two and three flat swinging vanes has been carried out in this work.
Conventional horizontal axis small wind turbines are prohibitively costly and mostly based on imported sophisticated technology. This does not allow extensive use in our country for small scale, individual purpose. Apart from this, the efficient high cost wind mills require comparitively large starting wind velocity, which is not available in many states of India.
Considering all these, the development of an extremely simple vertical axis type wind mill using a new concept of few swinging vanes has been undertaken. This rotor is analyzed for performance coefficients and the results are compared with available experimental data.
