I have some trouble or maybe it is better to called it I got some confusion about my result. I ran my simulations both with BEDDOES dynamic stall method and Steady dynamic stall. For each of them, I tried two methods to calculate my power.
In the first two simulations, I used RAMP wind speed:
[size=85]!Time Wind Wind Vert. Horiz. Vert. LinV Gust
! Speed Dir Speed Shear Shear Shear Speed
0.0 4.0 0.0 0.0 0.0 0.0 0.0 0.0
5.0 4.0 0.0 0.0 0.0 0.0 0.0 0.0
990.0 30.0 0.0 0.0 0.0 0.0 0.0 0.0
9999.9 30.0 0.0 0.0 0.0 0.0 0.0 0.0[/size]
and in the next two simulations, I used different deterministic wind speeds (4 m/s up to 21 m/s)
Finally, when I compare the results, the simulations results of different deterministic wind speed with BEDDOES dynamic stall are different with the others. On the other hand, the rest of results are approximately equal to each other (i.e. deterministic wind speed with Steady Stall method is similar to RAMP wind speed Steady and BEDDOES stall method)
Now I got confused that which one of them could be correct. By the way I need to mention that I check the angle of attack along my blade and it has a good margin to the stall region, that is, the angle of attack along the blade vary at very low angles.
Could you please advise me about BEDDOES dynamic stall method in FAST?
Thank you very much in advance for your help and your time.
PS: I wanted to attach couple of my plots but it seems it is not possible.
