The Performance of Savonius Windmill With Guide Vane [PDF]

Conference SENATIK STT Adisutjipto Yogyakarta, 2018
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

Performance of Savonius Rotor with Slits in the Blades.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1993
This paper is focused on the improvement of the performance of the Savonius rotor. For this purpose, the flow inside and outside the rotor is observed by means of a flow visualization method. The behavior of the vortices shed from both sides of the rotor is measured by means of hot-wire flow velocity meters.
