Hello
I use chtMultiRegionSimpleFoam solver. My case is very simple. I have a box 1x1x2m with two aeras (hot and cold air) and baffle. I want to have steady state solution, and I think there is only one solition for my case (heat flow through baffle until temperatures in two aeras are the same). But if I change the value of kappa in thermophysicalProperties for solid I have different final temperature in my box (!) hotair >>> 400 K cold air >>> 300 K kappa=80 >>> T_final~310 kappa=8 >>> T_final~340 kappa=800 >>> T_final~300 Does anyone can help? Why kappa (thermal conductivity) change my steady-state solution? Other variables in thermophysicalProperties does not influence on solution... Case is very simple and small (1 Mb), ready to run: http://speedy.sh/4mGcf/my-case.zip |
