- •
We organised a workshop for validating state-of-the-art actuator-disc wake models.
- •
We used high-resolution stereo PIV experimental data as reference case.
- •
We examined the turbulent velocity field in the near wake.
- •
The vortex model predicts the wake expansion and the centreline velocity correctly.
- •
LES models do not predicts correctly the near-wake turbulence levels.
