Numerical study of improving Savonius turbine power coefficient by various blade shapes

Alexandria Engineering Journal, 2019
Many Modifications have been studied for classical Savonius wind turbines in the blade shape to improve the power efficiency. Four rotor blade modifications have been studied in the present study: classical, elliptical, using Fluent Adjoint solver and a ...

Performance analysis of an idealized Darrieus–Savonius combined vertical axis wind turbine

Wind Energy
To investigate the effect of force distributions of each turbine component on the power performance of the Darrieus–Savonius combined vertical axis wind turbine (hybrid VAWT), the hybrid VAWT is modeled as idealized turbine under various force ...

An Experimental Study on the Performance of Check Valve-Aided Savonius Wind Rotors with Semi-Circular Blade

International Journal of Technology
The Savonius wind turbine is perceived favorable for a small-scale application because it is simple, relatively inexpensive, insensitive to wind directions, and has a good self-starting ability.

Effect of curved geometrical aspects of Savonius rotor on turbine performance using factorial design analysis

Curved and Layered Structures
Electricity consumption is expected to increase significantly by 2050. It is essential to ensure that as the increase occurs, there is also a corresponding increase in the proportion of renewable energy sources in the electricity supply.

A Comparative Review of Vertical Axis Wind Turbine Designs: Savonius Rotor vs. Darrieus Rotor

Inventions
This paper reviews and analyzes three types of vertical-axis wind rotors: the classic Savonius, spiral Savonius, and Darrieus designs. Using numerical modeling methods, including computational fluid dynamics (CFD), their aerodynamic characteristics ...
