Abstract
Increasing electricity demand, concern about the environment, and scarcity of fossil fuels are propelling the present world towards renewable energy sources. Wind energy is one of the sustainable resources that have the potential to meet the escalating demand for power. The existing wind turbines come with many limitations which are affecting power generation. In this context, a new eccentric vertical axis wind turbine is proposed that has the attributes of both drag and lift-based turbines. The design aspects and detailed functioning of the turbine are discussed and the characteristics of the machine are predicted in the current study. It is observed that the proposed turbine is devoid of negative torque and its simulation demonstrates improved performance. The lift and drag coefficients of 0.529 and 0.0112 are obtained with the lift-to-drag ratio of 47.2. At a wind speed of 12 m/s, the proposed turbine produces 15.57 % more power than the H-bladed Darrieus rotor.
