MEXICO Wind Tunnel and Wind Turbine modelled in CFD

The MEXICO Experiment is reproduced in CFD, including the geometry of the wind
tunnel and the wind turbine rotor. The wind turbine is modelled both as a full rotor and as
an actuator disc. Various questions regarding the wind tunnel effects on the measurements
are investigated. As in a previous work carried out without modelling the wind tunnel,
the CFD methods are found to give satisfying agreement with the axial velocity deficit in
the wake. In agreement with the previous work, the blade loadings estimated from CFD
are found to be consistently larger than the ones estimated from measurements. In order
to investigate further this issue, the loadings estimated from measurement are used with
an actuator disc model. This approach gives a smaller wake deficit in comparison with the
measurements, which in turn tend to agree with the full rotor computation results.
