AVATAR works on aerodynamic

modelling of 10 MW+ turbines

• We simply don’t know if present aerodynamic models are

good enough to design 10MW+ turbines

• 10MW+ rotors violate assumptions in current aerodynamic

tools, e.g.:– Reynolds number effects,

– Compressibility effects

– Thick airfoils

– Flow transition and separation,

– (More) flexible blades

– Flow devices

• Hence 10MW+ designs fall outside the validated range of

current state of the art tools.

Avatar: Main objective

To bring the aerodynamic and fluid-structure models to a

next level and calibrate them for all relevant aspects of

large (10MW+) wind turbines

Problem: No 10 MW turbines on market

yet for validation

– Approach 1:

• Validate submodels against experiments, e.g:

• High Reynolds number measurements in a pressurized tunnel

– Approach 2:

• Models in AVATAR range from ‘engineering’ tools to CFD

• High fidelity models (and intermediate models) feed information towards

engineering models

– Demonstrate the value of the improved tools on 10 MW reference rotors

– INNWIND.EU Reference turbine

– AVATAR Reference turbine (‘aerodynamic challenging’)
