Flow accorss in-line tube banks.

I am doing a simulation for flow over in-line tube banks in ansys-fluent to compare with experimental.
I am facing a problem with heat transfer specifically, I have set a heat flux q=1511 w/m^2, and Tin=300k however minimal heat transfer occurs and the only change in temperature occurs on the tubes surface only which is very odd. I am using periodic boundaries in the y and z directions and velocity inlet for x-direction and pressure outlet.
the set-up is exactly the same as in the experiments, and the mesh is of high quality done using size functions to certain edges to get the cell-shape required.
I think fluent set-up has something missing which is causing no heat transfer.
I have attached pictures of the mesh and temperature contour.
does anyone have any idea how I can resolve this?
