The Effect of Add-Ons on Wind Turbine Blades,lift force and increases power production with 0.3–3% more AEP. Design of vortex generators depends mainly on fin height, fin angle, chordwise location, shape of fin, and spacing between fin pairs. Design of Gurney flaps depends mainly on height. A winglet at the tip of the blade reduces tip-loss an

Pragmatic Models: BEM with Engineering Add-Ons,topic are built around the Blade Element Momentum (BEM) theory. The Blade Element Momentum theory in itself is very basic, e.g., it is derived for two-dimensional, stationary, homogenous, and non-yawed conditions. For this reason, several engineering models have been developed which overcome these s

Aeroelastic Simulations Based on High-Fidelity CFD and CSD Models,e review of the state of the art is presented at the beginning, including engineering models. Since the aeroelastic models consist of a flow and a structural solver, a detailed description of the modeling and simulation techniques is provided, including the basic requirement for coupling a computati

Aeroelastic Stability Models,in instabilities are explained, possible resonances addressed, and methods to analyze and improve the stability of a wind turbine design are discussed. The main instabilities that current size wind turbines could suffer from are stall-induced vibrations (edgewise and flapwise, idling instabilities,

Wind Tunnel Wall Corrections for Two-Dimensional Testing up to Large Angles of Attack,terference effects that exist due to the presence of the wind tunnel walls. This chapter discusses the most commonly used correction schemes both for streamlined and separated flow regimes. The classical correction method based on small velocity perturbations gives very good results up to angles of

3D Wind Tunnel Experiments, measurements can be implemented with less effort, and the overall uncertainty about data is generally lower since environmental conditions are precisely controlled. Progress in wind tunnel experiments and the quality of resulting measurements is closely related to technology of wind turbine models.
