Hello dear CFD pro

I am simulating the axial rotor turbine. But instead of simulating the 3d model I took a cross section and simulated in 2d. Obtained the DFBI momentum report (which turned out to be extremely low).

I am wondering if I can extrapolate the 2d result into 3d in order to know the torque of the whole rotor (instead of one its' 2d section).

more practical question: how deep is Z coordinate in 2d domain? say its 1mm deep, so if I have a rotor of 20 mm long so I just multiply the 2d result x20?

Thanx in advance
