Effect of Savonius blade height on the performance of a hybrid Darrieus-Savonius wind turbine

Journal of Mechanical Engineering and Sciences, 2019
A vertical hybrid turbine commonly consists of a Darrieus and Savonius rotor where the Savonius is inside Darrieus turbine. This paper describes the experimental study of hybrid Darrieus-Savonius wind turbines by variation in Savonius blade height.

Investigation of an innovative savonius turbine in practice. [PDF]

Sci Rep
Abstract The current study recommends a novel design that includes lightweight flapping gates that open when the convex side is facing the wind source in order to reduce negative torque and increase the efficiency of Savonius wind turbines. Very light leaf or torsional springs can be used to ensure that the gates close smoothly by returning ...

CFD investigation on wind power harvesting from small-scale wind turbines for powering residential buildings in New Zealand. [PDF]

J R Soc N Z
ABSTRACT As an alternative solution, wind power could be harnessed by designing and implementing small‐scale wind turbines for distributed power generation. In this work, 3‐dimensional time‐domain numerical simulations, based on the Reynolds‐Average Navier‐Strokes (RANS) model, are conducted for two categories of small‐scale wind turbines, i.e.
