Hello everyone,
I recently tried to shape smoke turns in an ole stove. for those who do not know what they are of the stoves that thanks to the smoke turns they manage to accumulate the heat of the combustion gases and release it in the surrounding environment gradually.
my package is version 13 of the workbench.
in my modeling (2d) I took a single section of smoke lap by placing as board conditions the temperature of the fluid passing through the section, and its speed! But now I have a big doubt about the "wall" that is my inner wall of the heat sinker or smoke lap that you want. I don't know how to shape the wall thickness! the functions "define wall thickness" is not applicable to my case (2d, density based, k-eps, etc., as the same manual says), in fact then in the boudary condition let me specify the temperature of the wall in contact with the fluid, which would not reflect for nothing (or almost) my starting problem! I therefore ask you a few tips to solve the problem.

I hope to have been clear enough if you want screen or other talk!

Thank you!
