Thoroughly examines the measurement, modeling and design approaches of wind turbine and wind farm aerodynamics Includes outlooks on the promising topics for future research Contains contributions of internationally renowned experts

Wind turbine aerodynamics remains to be a central field in the development of wind turbines. It comprises several aspects, and methods to be understood really make the best use of it in today’s wind turbine and wind farm development. This chapter gives an overview of all aspects in wind energy aerodynamics …

The dynamic inflow effect denotes the unsteady aerodynamic response to fast changes in rotor loading due to a gradual adaption of the wake. This does lead to load overshoots. The objective of the paper was to increase the understanding of that effect based on pitch step experiments on a 1.8 m diameter …

This chapter discusses several aspects related to engineering methods in wind turbine design codes. Current engineering models for rotor aerodynamics 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, …

In this presentation a new EA Wind Task is presented, i.e. an international cooperative project on the field of aerodynamic wind turbine measurements organised under auspices of the IEA

This paper assesses wind resource characteristics and energy yield for micro wind turbines integrated on noise barriers. An experimental set-up with sonic anemometers placed on top of the barrier in reference positions is realized. The effect on wind speed magnitude, inflow angle and turbulence intensity …

This research proposes new structural lay-outs for large wind turbine blades. The lay-outs were found by an optimisation method where the aerodynamics of wind turbine blades was combined with the structural model of the blade, formulated in a corotational framework. The aeroelastic blade loads were calculated …
