DISTRIBUSI TEKANAN PADA TURBIN ANGIN SAVONIUS DENGAN PENAMBAHAN VARIASI PANJANG DEFLEKTOR BOX

Abstract

Energy use in Indonesia still relies on petroleum, even though there are still many unused energy resources. So far, the exploration of energy resources has mostly focused on non-renewable energy, while renewable energy has not been widely utilized. One of the new renewable energy resources that has the potential to be developed is wind, the wind speed in Indonesia ranges from 3m/s-6m/s. The savonius wind turbine is a device that converts wind energy into mechanical energy in the form of drag force or lift force. To increase the coefficient of this turbine, you can add a box and vary the length of the deflector or wind direction. With the addition of this deflector length can have a major effect on the pressure coefficient and pressure characteristics of the wind turbine. The model in this study is a Swirling Savonius wind turbine with a stationary state with free variations, namely without box, without variation, length variation 5 cm, length variation 15 cm and length variation 25 cm. The results showed that the 25 cm length variation resulted in the best coefficient pressure (Cp) of 1.555266 and the pressure distribution characteristics of  of 8.18732,  of 14,41829 and  of 17,47907.
