NREL 5-MW reference turbine

Wind & Water Rotor Aerodynamics

I’m not sure if this is the right place for this question, but am taking a chance anyway.
Is the power or torque curve data for the NREL 5-MW reference turbine given in table form anywhere?

Dear Matthew,

Are you asking for the numerical data used to make Figure 9-1 from the following report, or something else: nrel.gov/docs/fy09osti/38060.pdf?

Best regards,

Yes. Exactly what I was looking for.

Dear Matthew,

I’ve included the numerical data used to make that figure in the attached text file.

Enjoy!

Thank you. :slight_smile:

Hi,

I downloaded the file “WindSpeedRelationships.txt”. The data for the rated wind speed is missing. I need to know in particular the maximum thrust. I read in an article that it is 827 kN. Would it be possible to get confirmation of this information? Thank you.

Regards

Dear Jessica,

I’ve attached the same table, but with a finer resolution between 10-12 m/s.

Please note that RotThrust in this table is the axial force along the (tilted) shaft, and so, does include some contribution from rotor weight, i.e., RotThrust is not the pure applied aerodynamic thrust.

Great, thank you for answering so quickly. And for pointing out that the values RotThrust were not the pure aerodynamic thrust. It explains to me why in certain sources I found values much lower than in this table…

Dear Mr. Jonkman,

what are the conditions under which these data are obtained (steady/unsteady aero, tower effects, blade/tower deformability…).

Thanks in advance,
Best regards,

Dear Matteo,

This is the data plotted in Figure 9-1 of the NREL 5-MW baseline wind turbine specification report: nrel.gov/docs/fy09osti/38060.pdf. From that report:

Thank you very much!

Have a nice day,

Dear Mr. Jonkman and others

The power and torque data from Figure 9-1 of the NREL 5MW report (as posted by Mr. Jonkman earlier in this topic) is from simulations that took the elasticity of the blades into account, if I’m correct.

The framework I’m using doesn’t include a aeroelastic code and such I’m searching for the rigid power and thrust curve. Do you by any chance also have the numerical data for rigid blade simulations? Or do you have knowledge of a report or paper including the data I seek?

Kind regards
Abraham

Dear @Abraham.Belderbos,

That is correct; the figure you reference includes the effects of elasticity. I don’t have the exact same plots without elasticity, but I would expect the elastic affects to be small. Of course, you can always regenerate the data with a rigid turbine by rerunning the simulations in OpenFAST.

The following forum topic may be of interest to you: NREL 5-MW reference turbine - CP, CQ, CT Coefficients - #23 by Jason.Jonkman.

Hello everyone,

Does anyone know where I can obtain the 3D geometry model of 5-MW reference turbine that can be read by Solidworks or Abaqus software? I hope to use solid or shell elements to create the wind turbine model.

Thank you

Dear @Xiaogang.Huang,

These details where not part of the original specification of the NREL 5-MW baseline wind turbine. However, the blade properties of the NREL 5-MW baseline turbine have been reverse-engineered in order to establish cross sectional details such as geometries and materials, as well as a full 3D FEA model, e.g., as discussed in the following forum topic: Structural design of the wind turbine blade.

Best regards,

Dear Jason

I also cannot find the report describing the reverse-engineered NREL blade properties from the link “Web Login Service - Error”.

It will be highly helpful if you could send a copy to my email.

My email is Xiaogang_Huang@hotmail.com

Thank you very much.

I have sent you the file via e-mail.
