Hi, I am working on simulation of a concentric tube heat exchanger with varying materials. I need to show that copper is a better material than steel for a heat exchanger. In order to achieve the same what are the boundary conditions i need to give in ansys fluent? I have a design of the concentric tube, i will give material properties to make it copper, followed by steel. But what should be the boundary condtions? is it sufficient to give only inlet velocity and temperature for steam and water? And the outlet conditions i l get after running the simulation. Plz suggest me the appropriate boundary condtions.

Thanking You
