Scaling the NREL 5MW Turbine Model
Quote from Kento Eiraku on 7. August 2026, 12:00Hello,
I am currently creating a scaled-up NREL 5MW turbine model in QBlade for a study comparing the performance of multiple wind turbines with a single large wind turbine.
Currently, I have modified the following parameters.
Blade Definition
- Position
- Hub Radius
- Chord
Structural Definition (.str)
- HAWT TURBINE CONFIGURATION (OVERHANG, TWR2SHFT)
- Hub and Nacelle parameters
- Drivetrain parameters (GENINER, DTTORSPR, DTTORDMP)
- BLADE DATA (MASSD, EIx, EIy, EA, GJ, GA)
I am also working on the TUB Controller parameters. However, before tuning the controller, I would first like to confirm that my structural model has been set up appropriately.
I have two questions.
- When scaling up the NREL 5 MW turbine, are these the appropriate parameters to modify? Are there any additional parameters that should also be changed?
- Currently, I am scaling these parameters using geometric similarity. Is this an appropriate approach for a comparative study, or would you recommend a different modeling or scaling method in QBlade?
Thank you very much for your time and advice.
