Abstract

Savonius wind turbine have the lowest efficientcy compared to other wind turbines. Based on the previous research, additional interfering cylinder and fin to the turbine was less efficient so there is still an opportunity to improved. Based on this condition, the experimental study was carried out by adding 1 fin to each turbine blade and placing an interfering cylinder in front returning blade to determine its improvement. It aslso compared between both of them in the experimental also used the myring equation n=1. Wind turbine dimension was 40 cm and variation of interfering cylinder diameter ratio was ds/d = 0,4;0,5;0,6; and 0,7. The speed variation was 5 m/s, 6 m/s and 7 m/s. The best performance of the savonius myring n=1 wind turbine is obtained at ds/d = 0,4 at a speed of 6 m/s. The coefficient of torque (Ct) performance increase 21.47% and the coefficient of power (Cp) 89.80%

Abstract

The Savonius wind turbines convert wind energy into electrical energy. Unfortunately,these turbines have lower performance than other types of turbines. In previous research, additiondisturbance cylinder in front of the returning blade with the addition of 1 fin on the blade has beenproven to increase the performance of the turbine. Although the increase not optimal. Based on aboveproblems, and experimental study was carried out placing the fins and the interfering cylinder at thesame place and time. This experiment uses a savonius turbine with n=1 myring type fins. Turbineblade height and diameter of 40 cm. Variation of interfering cylinder distance S/d = 1.4; 1.7; 2.0; and2,3. The test uses variations in wind speed of 5 m/s; 6m/s; and 7 m/s and carried out 12 times todetermine the effect of adding interfering cylinders and fins at the turbine blades to coefficient ofpower (Cp) and the coefficient of torque (Ct). The end result shows that the best performanceimprovement the savonius wind turbine occurs in variation the interfering cylinder distance ratio S/d= 1.4 at a wind speed of 6 m/s. The increase in the coefficient of torque.(Ct) is 15.01% and coefficientof power (Cp) is 89.95% for turbines without interfering cylinders.......

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 i.e 45°, 50°, 55°, and 60°. Its wind speed variations are 5 m/s, 6 m/s, and 7 m/s. The final results show that the best performance improvement of the turbine occurs at 60° stagger angle and 6 m/s wind speed. 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

Abstract

Savonius wind turbines are widely used for wind energy utilization eventhough theirperformance is considered lower than other types of turbines. In 3 previous studies, additionaldisturbance cylinder in front of returning blade and additional fin on blade could improve the turbineperformance but the increase was not optimum. Based on these problems, this experimental study usedone additional fin type myring n = 1 on the blade. Circular cylinders have a distance ratio of 340 mm,with various airspeed of 7 m/s, 6 m/s, 5 m/s, and various cylinder angles of 45°, 50°, 55°, 60°. Theexperiment was performed 12 times to determine the effect to coefficient of power (Cp) and coefficientof torque (Ct). The turbine best performance is obtained at a cylinder angle of 60° and a wind speed of6 m/s. The results are 0.394 for coefficient of power (Cp) and 0.688

Abstract

Previous experiment has been carried out on Savonius wind turbine with additionaloverlap ratio and variation of circular cylinder stagger angle to improve its performance.However, the experiment didn’t show flow visualization around the turbine. Therefore,numerical simulation using Computational Fluid Dynamics (CFD) method must be carried outto validate the experiment result and obtain the best performance and flow visualization ofoverlap Savonius wind turbine. The turbine simulated has an overlap ratio of 0,3. Then, thecircular cylinder is placed in front of returning blade with a distance ratio (S/d) 1.7 andvarious stagger angle of 45 ?, 50 ?, 55 ? and 60 ?. The flow velocity used is 5 m/s. Turbulencemodel used in this simulation is k-epsilon realizable with transient pressure based. The finalresult is overlap Savonius wind turbine with circular cylinder has increased its performance of31,56 % compared with overlap Savonius wind turbine without circular cylinder. The bestperformance occurs at 55 ? circular cylinder stagger angle in front of returning blade with0,4118 Coefficient of Power (Cp) value. The flow visualization shows that 55 ? circular cylinderstagger angle is able to create the most optimum nozzle effect.

Abstract

The performance of Savonius wind turbine has increased in the previous experimentalstudies with 1 additional fin and various disturbing cylinder distance in front of returning blade.Although the performance has increased, validation is needed through experiments . Therefore, furtherresearch is needed. The research uses Computational Fluid Dynamic (CFD) with 3-dimensional modelto obtain an increase on the turbine performance. In this simulation the solver chosen is pressure based with transient time mode. In the Savonius wind turbine simulation, the model used is the realizable k-epsilon model. Numerical method can validate experimental study. The turbine uses 1 additional fin with 40 cm in diameter and height. The variation of disturbing cylinder distance is S/d = 1.4 ; S/d =1.7; s/d = 2.0; s/d = 2.3 with wind speed of 5 m/s. Simulations are also carried out to determine thevalue of Coefficient of Power (Cp). The final result is there is 5,40% increase on the turbineperformance at the distance S/d = 1,7 , 5 m/s speed, and 1,0 TSR. The Coefficient of Power (Cp)simulation value is 0,389.
