Abstract

Clean energy harvesting and usage has gained considerable attention in the last few decades. While the horizontal axis wind turbines have been used extensively, they have certain defects and functional limitations. In the present paper, a novel oscillatory wind turbine is proposed. The conceptual design of the new turbine together with its configuration is explained. Dynamical equations of the turbine are derived and numerical analysis of these equations is performed using a developed computer code. The simulated behavior of the oscillatory turbine agrees well with the general behavior of the wind turbines, and the values for the power coefficient are acceptable for a micro-sized wind turbine.
