Measurement and analysis for the improvement of efficiency and power of Savonius vertical axis wind turbines without dimples and fins

Abstract

Energy effective approaches to improve the extraction of work from different sources of renewable energy are still appreciated in this energy starved world. Wind energy is one such widely used source. Wind energy is one of the world's most rapidly expanding electricity industries and most exciting alternative energy sources. A. Crespo, J. Hernandez, and S. Frandsen, “Survey of modelling methods for wind turbine wakes and wind farms Wind turbine technology is a method for converting wind kinetic energy into electrical energy. Efforts have been made in recent years to increase the capacity and reliability of standard Savonius VAWTs, which are not only easy to create but can also be used as a renewable energy source to meet the needs of rural areas with low power consumption. A.J. Alexander, B.P. Holownia Wind tunnel tests on a Savonius rotor; Journal of Industrial Aerodynamics In this present research paper, we analysis for the improvement of Efficiency and the power of the Savonius type wind turbine without using dimples on their blades and fins for more pressure generation Akwa, J. V., Vielmo et al., Review on the Performance of Savonius Wind Turbines“, Renewable and Sustainable Energy. the Savonius vertical axis wind turbine could be a safer alternative because it can also work in low wind conditions The aim of this model is to demonstrate its performance in varying wind conditions as opposed to the conventional horizontal axis wind turbine, and to contribute to its steady increasing popularity as a reliable source of power generation in the near future.
