Modeling passive variable pitch cross flow hydrokinetic turbines to maximize performance and smooth operation

L Lazauskas, BK Kirke- Renewable Energy, September 2012

► Modeling of passive variable pitch Darrieus hydrokinetic turbines predicts. ► High starting torque. ► Peak efficiency 50% higher than for fixed pitch turbines. ► Optimization reduces shaking to 1/3 that for fixed pitch turbines.
