epsilon=0.09^(3./4.) * k ^(3./2.) / (D*Lt)
where U is average velocity (same one used for reynolds calculation), I the intensity I gave 0.1 and Lt equal to the diameter.
for the geometry is a tube of 0.05 diameter and 1 m of length with a static mixer at the entrance (not at the inlet exactly but a little bit after)
for the cyclic, I am using cyclicAMI with perfect match min and max weights are 1 (it is a structured mesh), I didnt use cyclic alone as I wanted more general for cases that there will be a mismatch between the two patches.
I created a small cellZone almost at the outlet (at 0.75 to 0.85 in axial direction) and using fvOptions with momentumSource for the cycling.
momentumSource
{
type meanVelocityForce;
selectionMode cellZone;
cellZone AMIZone;
fields (U);
Ubar (0 0 0.7999999999999999);
}
the mesh has a good quality, with boundary layers on the walls (I will share the log of checkMesh after).
the case does not diverge but does not converge at all....
the geometry looks like this:

epsilon=0.09^(3./4.) * k ^(3./2.) / (D*Lt) *safetyFactor^3
where U is average velocity (same one used for reynolds calculation), I the intensity I gave 0.1 and Lt equal to the diameter. and safetyFactor=5
so the initial k and epislon are ==0.24 and 7.72785 (nut was calculated)
