Abstract:
This report describes the work performed within the IEA Annex XIV ?FieldRotor Aerodynamics? and its successor IEA Annex XVIII ?Enhanced Field
Rotor Aerodynamics Database?.
In these Annexes 7 organisations from 6 different countries collaborated
in performing aerodynamic experimental programs on full scale horizontal
axis wind turbines at field conditions. In such experimental programs
local aerodynamic quantities (forces, velocities) are measured at several
locations along a rotor blade. The following organisations (and persons)
cooperated in the projects:
- Netherlands Energy Research Foundation (ECN, NL) (Operating Agent)
J.G. Schepers, A.J. Brand;
- Centre for Renewable Energy Systems, (CRES, Gr, N. Stefanatos; Only
participant in IEA Annex XVIII);
- Delft University of Technology (DUT, NL): A. Bruining
- Imperial College (IC, UK), together with Rutherford Appleton Laboratory
(RAL, UK): J.M.R. Graham, D.G. Infield, R.J.H Paynter (only participant
in Annex XIV);
- Mie University (Mie, Jp, Y. Shimizu and T. Maeda; Only participant
in IEA Annex XVIII);
- National Renewable Energy Laboratory (NREL, USA): D.A. Simms, M.M.
Hand;
- Risø National Laboratory (Risø, DK): H.A. Madsen.
As a result of the international collaboration within the IEA Annexes
it has been possible to coordinate data processing and to crate and
maintain a database of measured data from all participants in a common
file format. The database is stroed on CD-ROM or accessible through
Internet. In principle the database is available for outside parties.
The detailed aerodynamic measurements obtained on very different turbines,
give a unique opportunity to better understand the aerodynamic behaviour
of a wind turbine. This may result in the development and validation
of more accurate aerodynamic models.
