Abstract

This paper investigates the performance of Savonius vertical axis water turbine by varying its stagger angles. In this study, the shape of the turbine blade is modified based on the Myring equation as well as adding a disturbance in the form of a circular cylinder placed in front of the advancing blade as a barrier. The method used in this research is an experimental study in a water tunnel at a velocity of 0.22 m/s. The turbine has size of 0.4 m in height and 0.4 m in diameter. The experiment results show that the use of a circular cylinder in front of the advancing blade has a significant effect on increasing turbine performance. This can be proven by placing a circular cylinder with , , and where the angular speed achieved is , torque coefficient and the result of maximum power coefficient is about 0.4356.

Abstract

The wind energy is the one of the renewable energy to produce the power using turbine. The Savonius turbine have lower performance compared to the other. In this work, the method used is the experimental stu using the wind tunnel to flow air go to the Savonius turbine. The model used is a conventional Savonius wind turbine by adding cylinder installed in front of advancing area with a diameter of 0.4 m and a height of 0.4 m and ds/d of 0.1, 0.2, 0.3, and 0.4 with the rotation of 20 rpm at a stagger angle of 0°, 30°, 60°, and 90°. The experiment is kept constant at the velocity of 7 m/s. This work objective will determine the torque and power coefficient by varying the diameter and stagger angle. The results show that the biggest performance decreased was about 40% in the variation of ds/d of 0.3 with a stagger angle of 0°. The best results show that the wind turbine performance occurred the highest improvement in about 12% at the variation of ds/d = 0.4 with a stagger angle of 60°.

Abstract

The previous Savonius wind turbine studies have proved that overlap modifications to conventional blades can improve turbine performance. With these conventional blades, the performance is less optimum because the drag force generated by turbine's rotation is still high. Based on this condition, this experiment is conducted by modifying Savonius wind turbine with overlap blades using Myring equation n = 1. Its blade profile is made half-elliptical to reduce drag force. Diameter and height of the turbine are 400 mm with 0.3 overlap ratio. The ratio of cylinder diameter (ds/D) is 0.4, and the ratio of cylinder center distance (S/d) is 1.7. Experiments are conducted by varying stagger angles of circular cylinder in front of returning blade are 45°, 50°, 55°, and 60° with velocity 5 m/s. The final results show that the best performance improvement of the turbine occurs at 60° stagger angle. The increase in torque coefficient is 4.95% and power coefficient is 20.16% to overlap Savonius wind turbine with myring n = 1 with no circular cylinder.
