Inquiry About IEA Task 29 Mexnext Aeroelastic Code Availability

Wind & Water Structural Analysis
1

Hello,
I hope this message finds you well. I would like to use the wind tunnel test data provided in the technical report for IEA Task 29 Mexnext. However, I have been unable to locate the aeroelastic code for this model. Is it open-source? If so, could you please provide me with the GitHub link or direct me to where I can access it?

Best regards,
Dereje

Dear @Dereje.Haile,

Can you clarify what you are asking for?

For the Mexnext wind tunnel data, I would ask Gerard Schepers of TNO.

For the aeroelastic code, I’m not sure what you are asking about.

Best regards,

I want simulation results from the MEXICO wind tunnel test, including:

  1. The MEXICO power coefficient and axial force coefficient.
  2. The MEXICO flapwise fatigue-equivalent blade root bending moment at different yaw angles.
  3. The MEXICO normal force variation as a function of azimuth angle.

I want to conduct a simulation for the NREL 5MW wind turbine, but I am unsure if I can compare the NREL 5MW wind turbine model simulation results with the MEXICO wind tunnel test data.

Q1: By setting the same tip speed ratio for my model, can I use the NREL 5MW wind turbine model simulation results to validate them against the MEXICO wind tunnel measurements?

Best regards,
Dereje

Dear @Dereje.Haile,

The NREL 5-MW baseline wind turbine is not the same turbine as used in the MEXICO wind tunnel tests (even when considering consistent scaling in rotor size), so, “no”, you wouldn’t be able to reasonably compare the results between the two.

For the MEXICO data, I would ask Gerard Schepers of TNO.

Best regards,

Thank you for the clarification. Which wind turbine model results should I use to validate against the MEXICO wind tunnel tests?

Dear @Dereje.Haile,

I was not involved in the MEXICO phase of IEA Wind Task 29 (MexNext) and don’t have an OpenFAST model of that turbine to share. There could be an OpenFAST model that has been developed of this turbine by someone, but I’m not sure who would have it. Again, this is probably a better question for Gerard Schepers. If you have the properties of this turbine, you could also put together the OpenFAST model yourself.

Best regards,

I will ask Prof. Gerard Schepers. Thank you!

Best regards,
Dereje
