3D natural convection with fluid "box"

Please login with a confirmed email address before reporting spam

Hi, please help.

I'm using conjugate heat transfer interface to solve solid-fluid heat transfer problem. I have solid heat source surrounded by a rectangular air "box". I'm interested in convective fluid flows. How should I set up my model correctly?

I'm using open boundaries on air "box" boundaries. Is this approach correct (with no inlet, outlet and outfow BC)?

And how many open boundary BCs shouls I use? Only 2 (top ant bottom) or 6 (for all air "box" boundaries)?
