Abstract
An EERA (European Energy Research Alliance) consortium started an ambitious EU
FP7 project AVATAR (AdVanced Aerodynamic Tools of lArge Rotors) in November 2013.
The project lasts 4 years and is carried out in a consortium with 11 research institutes and
two industry partners. The motivation for the AVATAR project lies in the fact that future
10 to 20 MW turbine design model analysis will importantly violate known validity limits of
today’s aerodynamic and aero-elastic models in aspects like compressibility and Reynolds
number effects, laminar/turbulent transition and separation effects, all in combination with
a much more complex fluid-structure interaction. Further complications enter by the
possible use of active or passive flow devices. AVATAR's main aim is then to develop
enhancements for aerodynamic and aero-elastic models suitable for large (10MW+) wind
turbines analysis. The turbine modelling improvements will be demonstrated on a new
10MW reference turbine design model description. The first results from the AVATAR
project are presented in this paper.
