Sounds like a straight forward conjugate heat transfer (CHT) simulation. There has been lots of posts on how to do this. Also the tutorial examples are good, I think the heating coil example would be relevant to you.

I'm sorry, but I somehow can not choose two fluids and the temperature distribution in the walls are not visible. If you are not difficult, can help to understand.

Please post images on the forum. I cannot see the link you posted.

If you have two fluids then you have a multiphase model as well. Is this correct?

Hi hottern,

Saw the image posted by you. Your problem is multiphase with heat transfer. Two phases involved are air & water. There are good tutorials to understand the multiphase problems. You may try "Tutorial 15: Multiphase Flow in Mixing Vessel".

Good luck.
