Abstract
En 中文
• Coupled flutter of wind turbine blades is numerically investigated. • Partially correlated and rotationally sampled turbulence field is simulated. • Uncertainty in aeroelastic load properties of the blade is concurrently studied. • Both uncertainties are examined by stochastic dynamic stability. • The combination of partial turbulence correlation and load variability can reduce flutter angular speed by 20%.
