The Performance of Savonius Windmill With Guide Vane

Budi Sugiharto

Abstract


This paper aims to observed the performance of Savonius windmills with 16 guide vanes with variations in the guide vane angle of 30 °, 45 ° and 60 °. Tests are carried out openly with the help of a fan as a source of air flow. The best performance results obtained at wind speeds of 5 m / s, namely the highest power coefficient occurs on the mill with a 45 ° angled guide vane of 24%. The highest torque coefficient is owned by a windmill with a 45 ° angular guide vane of 20% at a rotational speed of 100 rpm.
