Optimizing a Novel Wind Turbine for Sub‐Saharan Africa: A Techno‐Economic and Multicriteria Evaluation

open access: yesInternational Journal of Energy Research, Volume 2025, Issue 1, 2025.
Wind energy has emerged as a key contributor to the global renewable energy mix, yet much of sub‐Saharan Africa (SSA) remains underutilized due to predominantly low wind speeds and the limitations of conventional horizontal‐axis wind turbines (HAWTs).

Optimisation of vertical axis wind turbines [PDF]

open access: yes
A practical Vertical Axis Wind Turbine (VAWTs) based on a Darrieus rotor has been designed and tested and found to be capable of self-starting at wind speeds above 4m/s. The self-start feature has been achieved by replacing the usual symmetrical aerofoil

Blade force measurement and flow visualization of Savonius rotors.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1985
For the purpose of clarifying the mechanism of rotation of Savonius rotors, ones which have two semicylindrical blades are studied experimentally. The force acting on a blade is measured in a water two tank for both cases where a rotor is at rest and rotated.

Response of a savonius rotor to unsteady flow [PDF]

open access: yes, 1974
A Savonius rotor used as a speed measuring device was subjected to a unidirectional unsteady flow having a mean value U0. A comparison between the rotor rotation rate in this unsteady flow and its rotation rate in a steady flow U0 yielded systematic ...

Modeling the Dynamics of a Catamaran Driven by a Savonius Rotor and a Propeller

open access: yesJournal of Computer and Systems Sciences International
The dynamics of a catamaran with a Savonius rotor and a propeller installed on it is considered. Under the action of a stationary wind flow the rotor rotates and transmit it to the the propeller, which creates thrust. As a control, the angle of the catamaran’s course relative to the wind flow is considered. The control task is to move the center of the
