Conjugate heat transfer with periodic heat condition

I am trying to solve a conjugate heat transfer problem with the fluid layer embedded in a solid layer and heat being generated in certain portions of the solid layer. The major challenge is that I want to implement periodic boundary conditions for the faces parallel to the inlet face and the faces parallel to the outlet face.
When I do that, the result I get indicates that the temperatures on the 2 sets of faces are the same which were chosen for periodic boundary condition (Solution 1 and Solution 2 in the attached file). Further when I implement thermal insulation boundary condition instead of periodic heat condition on the 2 sets of faces I get the same result (Solution 3).
Does that mean that periodic heat condition is the same as thermal insulation? That does not make a lot of sense to me. I was thinking that periodic heat condition allows matching of temperatures on the faces but allows the same heat flux to cross the boundary (which need not be 0).
Any suggestion regarding this would be greatly appreciated.
Regards,
Sumeet
