Question regarding thrst curve of the 5 MW

Wind & Water Rotor Aerodynamics
1

Hello @Jason.Jonkman,

Hope you are doing well.

1. Clarification on Figure 9-1 of the 5-MW Reference Turbine Report

In the NREL 5-MW wind turbine report (https://docs.nrel.gov/docs/fy09osti/38060.pdf), Figure 9-1 shows curves of:

  • Generator power
  • Rotor power
  • Generator speed
  • Rotor thrust
  • Rotor torque

…as functions of wind speed.

Could you clarify the simulation setup for that figure?

  • Were the simulations performed under steady wind conditions, or did they include turbulence?
  • Were the blades modeled as rigid or flexible?

Thank you in advance,

Best Regards,

Riad

Dear @Riad.Elhamoud,

This is explained in the text preceding Figure 9-1 in the NREL 5-MW specifications report, where it explains that separate simulations where computed under steady wind conditions with flexible blades (and other DOFs).

Best regards,
