Hello forum,


i am currently trying to do a coupled cf-thermal- simulation:


I have a pipe with a hot water flowing inside. The pipe-wall is 2 mm thick and i am interested in the steady- state temperature-field in that wall. Which boundary condition should i apply on the outer wall of the pipe?
Lets say the pipe-wall is made of aluminium and the outer medium is air at some temperature.
How do engineers solve that kind of problems?


Best regards.

Probably a convective boundary condition using an h from the closest possible case (buoyancy should certainly be accounted for).
