Optimization of a Nature-Inspired Shape for a Vertical Axis Wind Turbine through a Numerical Model and an Artificial Neural Network
Javier Blanco Damota,Juan de Dios Rodríguez García,Antonio COUCE CASANOVA,J. Telmo Miranda,Claudio Caccia,María Isabel Lamas Galdo +5 more
TL;DR: The present work proposes an artificial neural network (ANN) to analyze vertical axis wind turbines of the Savonius type, appropriate for low wind velocities due to their low starting torque, and found that the maximum power coefficient corresponds to aspect ratio 7.5, overlap/chord length ratio 0, and twist angle 112°.
