Wind tunnel simulation
Hi! I'm simulating my school's wind tunnel with the simpleFoam solver.
The results showed that, for example, velocities converge but do not correspond to those expected. The measurements taken in the tunnel return values ​​of between 1.5 and 2 m/s at the inlet, around 16 m/s in the working area and 2 m/s at the outlet, where the impeller is located. I expected values ​​close to these ones, but the simulation returns higher values.

I ask you if you can give me some information to find out where the error is.

Here are the p and U files:

Here are the fvSchemes, fvSolution, RASProperties and transportProperties files:

Here are some pictures of the results:
