The purpose of my project is to simulate the evolution of the temperature in a room heated by radiators. I have a little problem with the condition I have to put on my windows. I would like to put a condition to simulate closed windows. Also, I don’t understand how I should use the condition “natural convection inlet/outlet boundary”.
Thanks for posting your question!
One of the ways to simulate closed windows in CHT is using wall boundary condition enabling radiation, then you will be able to consider the external wall heat flux, ambient temperature, thermal conductivity of the windows (e.g.: if it is made of glass, etc). In this tutorial you have closed windows, so please take a look:
About natural convection inlet/outlet, we provide this detailed page on that:
