What are the accurate values to estimate the torque coefficient "Fluent" ?

Hi,

I am studing the performances of Darrieus wind turbine composed of three Naca profiles.

I have set these values at the "reference values" in order to estimate the torque coefficient. In fact, I suggest two possibilities. Could I have please your feedbacks.

Cheers,
the study is done on 2D

Possibility 1:

1 - Area: corde length * 3(number of blade) * 1 (depth)

2 - Depth: 1

3- Length: Radius of the rotor

Possibility 2:

1 - Area (swept area): diametre of the rotor * 1 (depth)

2 - Depth: 1

3- Length: Radius of the rotor
