Renewable energy development is increasingly important to anticipate the limited use of fossil energy and its impact on the environment. The Savonius turbine is a vertical axis turbine that can utilize flow from all directions with simple construction, so it has the potential to be developed as a wind turbine and hydrokinetic to generate electricity. This paper aims to conduct an experimental studied the same Savonius combined blade rotor as a wind turbine used in a wind tunnel and a hydrokinetic turbine in an irrigation channel.

Abstract:

Rice fields are areas that have irrigation and rarely have lighting; this is dangerous at night because wild animals such as snakes are difficult to see. Irrigation has low-scale water energy with low-head conditions; hence the Darrieus and Savonius type water turbines are considered suitable for this condition. However, until now, there has been no comprehensive study of the feasibility of the two turbines for irrigation flow. Hence this study presents the experimental work to explore the performances of the Darrieus turbines Two Blade Different Configuration and hybrid Darrieus-Savonius turb

Traditional Savonius wind rotor has simple structure and can operate in any wind direction. However, its aerodynamic efficiency is lower than other types. A novel S-shaped wind rotor with three blades is proposed in order to improve the aerodynamic performance. The blade of the rotor is composed of two opposing convex circular arcs and its shape likes an ‘S’. The flow characteristics of the rotor are studied and analyzed by computational fluid dynamics (CFD) numerical simulation method. The steady and transient performances are studied using SST k-ω model and sliding mesh method, and are compa

Abstract: Renewable energy sources are energy sources that can replace the use and use of fossil energy sources where they are very abundant and have not been widely used for their existence. Therefore, to bring up new ideas in terms of creating or changing renewable energy, there needs to be a match between the education curriculum and market needs. So to arouse the enthusiasm and motivation of students in the teaching and learning process, especially in the energy conversion machine course for mechanical engineering students, it needs media and learning methods.

Abstract:

Savonius, a type of vertical-axis wind turbine (VAWT), is suitable as an appropriate small-scale energy conversion apparatus for regions with relatively low wind speeds, such as Indonesia; however, it exhibits sub-optimal efficiency. One potential approach to improving the efficiency of Savonius turbines is to increase the drag force on the concave surface of the blades. In this case, the dissimilarity in the forces experienced by the two blades can be increased, resulting in a corresponding increase in torque. This investigation aims to assess and compare the power coefficient (Cp), torque an
