Hi everybody, I want to obtain a fully-developed profile at an inlet in one system based in 8 small pipes in counter current and Co-current inside in a bigger one. This is the geometry:



I got a developed profile in a velocity value making a periodic condition in the small pipes at the outlet (I have a developed profile in the inlet). But only the velocity. I need to get a fully developed profile of temperture, heat transfer, etc as well. Any ideas?

This is the developed profile of velocity at the inlet:



Thank you!
