Uniform CT Disk Validation with 1-D Momentum Theory

[StormMata]

Description

We are implementing the uniform CT disk in uniform inflow. In checking that we have set up the problem correctly, we have tried validating the velocity at the disk and in the wake against 1-D momentum theory. We find that both deviate from what we expect. A plot of the AMR-Wind centerline velocity is provided below with the expected values from momentum theory. We have tried tuning the epsilon parameter, but are unable to find a value that changes the results materially. Have others experienced similar issues with this disk model?
