Raditation through MLI – Thermal Desktop
-
-
Hi, I was trying to model heat transfer through MLI into a cryogenic tank in Thermal Desktop. Each MLI had to be modelled using thin shell elements for a separate purpose nut even before advancign I got a doubt as to whether this is the correct approach. The problem is defined below:
The 20 layer MLI heat transfer problem was solved using 20 thin shells because subsequent to this certain coolant channels had to be incorporated in between the MLI layers
However there is a doubt as to how the radiation heat transfer is getting solved, all the MLI layers were placed into a single radiation group “radiation_shield” and the space node was defined to be at 300K
I doubting if the interior layers will also be interacting with the space node, I would want only the outer most MLI to be interacting with the space node
