Crespo_hernandez turbulence model

[UnderMou]

Hello everyone.

I'm studying floris code so I can use it after and I'd like to check with you guys about the crespo-hernandez added tubulence model equation implementation in crespo_hernandez.py .
My question is regardin the line 86 where ambient turbulence intensity is powered by self.initial ,which takes default value of 0.1 (default_value).

I got confused because I was studying the original paper [1] and it brings the same equation but the turbulence intensity is powered by constant -0.0325.

Then I thought of the following:

ti = ( self.constant
* axial_induction ** self.ai
* ambient_TI ** (-0.0325)
* ((delta_x) / rotor_diameter) ** self.downstream
)

Another issue is on constant ... would you recommend if I change it to 0.73 as in the paper in my applications? the other constants of equation I understood.

Thanks in advance!
