Improved performances of the wind inlet of the Savonius rotor [PDF]

Vojnotehnicki glasnik, 2017
In this study we analyzed the design changes through increasing vertical angles of the top and bottom plates of the wind inlet of a Savonius rotor, in order to obtain better results and better system performances. A designed wind inlet is placed in the front part of the rotor in order to prevent negative torque opposing rotor rotation.

Optimization of a hydraulic Savonius turbine

, 2022
Ever-growing energy demand and unacceptable emissions from fossil fuel combustion are major driving forces for expanding alternative, green energy sources. Hydro-power is one promising ecological alternative to meet these energy requirements. Hydro-kinetic turbines produce energy from streaming fluids such as water. This work con-centrates only on water

Experimental Study on the Performance of Three Vertical Axis Hydrokinetic Turbines

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Vertical‐axis hydrokinetic turbines have shown remarkable potential as a renewable energy option. However, their hydrodynamic performance remains uncategorized under turbulent, sedimented river flow conditions. This study presents a thorough and systematic experimental investigation to understand the impact of induced flow dynamics on three primary ...
