Recommended or default UA constants per UAMod

Dear OpenFAST team,

I’m currently reviewing the implementation of the Beddoes–Leishman unsteady aerodynamic model in AeroDyn, comparing it against formulations and applications such as:

  • T.S. Beddoes, Practical Computation of Unsteady Lift
  • R. Pereira, G. Schepers, M. de Pavel, Validation of the Beddoes–Leishman Dynamic Stall Model for HAWTs using MEXICO data
  • J.G. Leishman, Principles of Helicopter Aerodynamics

In these documents, I found several of the parameters recommended by openfast for constants. I also found that GH Bladed explicitly recommends default values for these constants for different Unsteady Aerodynamic Models, as shown below:

So my question is the next one:

Could you please clarify if the same default constant values are recommended across all UAMod versions? Or are there any recommended constant sets specific to each UAMod?

Thank you once again for your time,

Kepa
