Always these values. It seems not the reason of mesh quality. Maybe some region of the mesh is coarser. I am trying to refine.

Dear all,
I've cut seven cross-sections along the length(1 m for each) and plotted their velocity vectors colored by temperature (up/letf is cfx result, bottom/right fluent).
We can see from the pictures, the different velocity direction leading to a mixture of hot and cold water. Obviously the mixing of cfx is severer than fluent. This may be the reason of severely temperature diffusion of cfx result.
I do not know which setting can lead to such a difference. Any suggestions?
Many thanks!

As I have said many times, something is creating too much diffusion.

Are you sure you entered the material properties correctly?
