Hi,
I have a irregular block with pipe flow within. Water is flowing through the pipe and the block surface is subjected to certain heat flux. I have successfully coupled these two physics (laminar flow and heat transfer in solids) together using non-isothermal flow node.
However, I need to study the effect of cooling the ambient air is having on the block. I made a larger block as the air domain. But when I assign this air domain in the previous laminar flow node(spf1), I was unable to assign inlet/outlet to the pipe within the block. And when I included the air domain in the first heat transfer node (ht1), the heat flux I assigned on the block becomes 'not applicable'.
Can someone point out how I should achieve coupling everything (including heat transfer and laminar flow in air, and ht and spf in block +pipe) together?
