Hi,
I run a simulation on an industrial project with hot process and natural convection.
I run like a Wind tunnel to have Wind effect with thermal analysis for the process (radiation on).
The result are not so bad now but there is rotation région on the external condition (0 Pascal).
The rotation is caused by thermal stratification.
May i have to put film coefficient to fix this issue ? 5W/m².K for 30°C
Only on the 0 pressure boundary condition ?
On the side and the top of the box ?
In this context, do I have to do it for the floor?
What about sliding boundary (on top and sides) with activated radiation (I already had problems with this condition)
If it's not the right solution, I'm listening to you
Thank you all
