A Novel Correlation Model For Horizontal Axis Wind Turbines Operating At High-Interference Flow Regimes, Anurag Rajan, Fernando L. Ponta

Department of Mechanical Engineering-Engineering Mechanics Publications

Driven by economics-of-scale factors, wind-turbine rotor sizes have increased formidably in recent years. Larger rotors with lighter blades of increased flexibility will experiment substantially higher levels of deformation. Future turbines will also incorporate advanced control strategies to widen the range of wind velocities over which energy is captured. These factors will extend turbine operational regimes, including flow states with high interference factors. In this paper we derive a new empirical relation to both improve and extend the range of Blade Element Momentum (BEM) models, when applied to high interference-factor regimes. In most BEM models, these flow regimes are modeled using ...
