I am trying to do a simulation for Solar trough using Ansys fluent
I have a parabolic trough that will be aluminum and contains the air domain in it around a copper pipe which has a water passing through it
my problem in how to give a boundary conditions because I have two domains

I think you have at least 4 domains.
- aluminium trough
- air in and around the trough
- copper pipe wall
- water in the copper pipe
Many solar water heaters have a clear glass plate on the top of the trough. That keeps the air trapped and would make this problem a bit simpler. Otherwise you have heated air leaving the trough.

what is I must study before doing this simulation I have some experience in cfd and it is my first step in radiation problems .and I searched about some tutorials about radiation and convection but I don't get the answer.

I can't see any shadow walls or non conformal interfaces: heat is not going to pass between zones.

Did you figure out the boundary conditions required to solve this problem? I am also looking for the same problem. If you have solved the problem, can you share the case file for the parabolic trough?
