Aerodynamic performance evaluation of multi inner blades savonius rotor
Savonius wind turbine is the cheapest and simplest type of vertical axis wind turbines. This turbine is being utilized in various countries due to the simplistic design and low construction cost. However, this turbine suffers from low efficiency. For that, this study aims to increase the …

Experimental and Numerical Investigations on Aerodynamic Characteristics of Savonius Wind Turbine with Various Overlap Ratios
Savonius wind turbine is the simplest type of vertical axis rotor that has a relatively low efficiency. Operation of the Savonius wind turbine is based on the difference of the drag force on its semi-spherical blades, depending on whether the wind is striking the convex or the concave part of the …

Experimental and simulation analysis for performance enhancement of elliptical savonius wind turbine by modifying blade shapes
Savonius turbines are drag-based rotors which operate due to a pressure difference between the advancing and retreating blades. After going through an exhaustive literature review, it was realized that the Savonius wind turbines are an applicable option at low wind speed areas, where the …

Optimization of a Savonius rotor vertical-axis wind turbine for use in water pumping systems in rural Honduras
… as designed. The novel modifications to the Savonius rotor that were made do not seem to improve its performance. Within the constraints of the installed components, the current rotor should perform well pending other changes. The most promising improvements to the system are weight reducing …

Vertical axis wind turbine with continuous blade angle adjustment
… greater than the efficiency of a typical Savonius wind turbine (CP ~~ 0.15), and it reaches CP = 0.5 at the limiting blade width, b = 2r. The analysis also predicts a static torque and optimal tip-speed ratio that are both greater than those of a Savonius wind turbine with similar blade …

Computational and Experimental Study on Vertical Axis Wind Turbine in Search for an Efficient Design
… match with the characteristics of Savonius type VAWT, such as good stall characteristics and little roughness effect, relatively high drag and low lift coefficient. Integration of Computational Fluid Dynamics (CFD) simulation and wind tunnel experimentation has made the current …
