Hallo to everybody!
I'm trying to realize the simulation of a metal box (fillled with air and including an heat source, and surrounded laterally by other boxes that I consider through the simmetry/boundary condition) that is cooled by a tube of water in contact with the box, but i have problem to set good boundary condition.
If I set the inlet temperature of the tube, and set external convection for the other surfaces of the box, i find that everywhere the temperture is close to the one of the inlet surface of the tube... the temperature boundary condition seem 'stronger' than any other boundary condition.
I find more realistic results if I set a different temperature (taken from experimental results) on one of the surfaces of the box, but I am not sure if that is correct, or I am just adding a new heat source that shouldn't be present.
do you have any suggestion?
