Thermal Transient - Wall

Thermal Transient - Wall

Thermal Transient - Wall

(OP)
Hello everyone,

I have recently using Ansys Fluent for transient thermal analysis. Currently, i have a major problem.

I have a wall, on the one side of the wall (interior side), I impose a temperature solicitation that raises over time (that is the boundary condition of that surface). I want to read the temperatures on the opposite side of the wall (exterior side).

What boundary condition or procedure should I put on the exterior side? If I put heat flux = 0, the temperature just builds up forever because I don't have any declared losses from that side of the wall. I have the experimental data, and the temperature on the interior side is approximately constant because in the lab I have the transference of the coming heat to the environment.

I can I replicate this? what is the boundary condition?

Thank you very much in advance
