Hey, everyone!

I am trying to simulate a fin and tube heat exchanger using Ansys Fluent and I'm trying to validate my numerical results with an experimental correlation from a paper, but I am getting results really far from what is expected and I think I found out why.

When setting my boundary conditions for the fin, I realized I'm working with the no-slip condition, but I am also setting heat flux as 0, so the fin is not being used for the main purpose, which is to help heat transfer. I've looked at all my boundary conditions options and I am really lost as to which one I should choose. Anyone has any idea of what I should do to get the appropriate results?
