hi everyone
i want to modelling a pipe which is located in the soil
there is the water in the pipe and heat transfer from the soil to the water
so there is 2 conduction which is happen in the soil and pipe ( or maby 3 because another material would be using between the soil and pipe) and a convection in the water

can anyone help me to do this ?

thanks

Nobody can help you unless you ask some specific questions.
Reply to your question should be something similar to this (#21):

sorry ghost82


the pipe is in the borehole and the heat transfer through the soil and pipe to the water
my question is how to coupled the conduction of soil and pipe with the convection of water?

If you model the solid soil and the water flowing in the pipe both conduction and convection are automatically taken into account. You have to couple wall and shadow-wall of the pipe-soil.
What are your boundary conditions?
