| 概要 |
This study aims to obtain the characteristics of the Savonius turbine based on the ratio of the inlet and outlet blades by using a modified blade shape and analyzing numerical simulations of the speed... and pressure around the turbine blades. The use of Savonius turbines can be a solution because it produces large torque even if installed at low wind speed. Savonius blade modification into a double blade with a combination of type L and U aims to capture greater wind energy while generating greater electrical power. The study was tested at speeds of 3, 5, 7, and 9 m/s with variable differences in the side in and out of the turbine. However, what is presented in this article is the test parameters at a wind speed of 7 m/s. The test obtained data in the form of torque, generator speed, voltage, and current produced by the turbine. Once analyzed it can be concluded that the best performance is produced by a single blade rotor, then the rotor is 1:1, 2:1, and the lowest performance is obtained from the 3:1 rotor. The results of the study indicate that the Savonius turbine has optimum performance on a single blade rotor model at 189 rpm, the power coefficient value is 0.039, turbine power is 80.26 W, generator power is 3.08, and system efficiency is 3.84%.続きを見る
