Hi, all

I want to model the cooling of a liquid metal inside a tube flowing under laminar conditions. Specifically I want to calculate the variation of the Nusselt number on the tube wall during the cooling phenomena. Can any one guide me what boundary conditions in terms of heat transfer should I use on the tube wall. I am using fixed inlet temperature and convective flux at the exit.

Kind regards

Hi

I would start considering NITF "conjugated heat flow" physics, checck the doc

Good luck
