Dear Foamers

I'm going to simulate a case like the one i've attached in this post.
There is a smaller tube which blows some air (turbulent) in the main flow of a bigger tube. The two flows from inlet1 and inlet2 has diffrent temperature and velocities. In reality the baffle is a steel pipe with a thickness of 5mm.

I want to know how the temperature profile on the baffle (in operation) looks. Therefor i can solve the whole thing steady-state.

I took a look on the diffrent solvers and read a few threads in this forum. Now i'm unceratin, which possibilitys i have.

-chtMultiRegionSimpleFoam:
In my opinion i don't have multiple regions?

-thermal baffle:
turbulentTemperatureCoupledBaffleMixed should be the right one?!

What i have tried: I have adapted the "circuitBoardCooling" Case.
But when i run the case, the temperature at the inlets does not spread into the geometry.Maybe i have done something wrong, or this solver is not the right one for my problem?

So this are my thoughts about the topic. If you could give me some inputs.. that would be great (to be precise: which solver would you choose?)
