dc.descriptionThis report aims to explore the potential of combining the Darrieus and Savonius vertical axis wind turbine (VAWT) designs to create a more efficient and versatile renewable energy solution. The Darrieus VAWT is known for its high efficiency in capturing wind energy, while the Savonius VAWT exhibits excellent self-starting capabilities and performs well in low wind conditions.
dc.description.abstractThis report aims to explore the potential of combining the Darrieus and Savonius vertical axis wind turbine (VAWT) designs to create a more efficient and versatile renewable energy solution. The Darrieus VAWT is known for its high efficiency in capturing wind energy, while the Savonius VAWT exhibits excellent self-starting capabilities and performs well in low wind conditions. By combining these two designs, we aim to leverage their respective advantages and overcome their individual limitations. The present report introduces a CFD analysis of a proposed hybrid VAWT using ANSYS Fluent and experimental analysis. Straight blade with airfoil profile S1046 was used for darrieus rotor. The hybrid rotor has a helical Savonius rotor with 3 Darrieus blades. The performance study of hybrid rotor at different radius ratios are carried out and highest power coefficient is achieved at 0.43 radius ratio. It is found that radius ratio greatly affects the performance of the turbine. The larger the diameter of Savonius rotor, more is the interaction of Savonius and Darrieus blades resulting loss in performance. The final optimized design is fabricated and experimentally tested.
