Heat Exchanger

Hi everybody

I'm modelling an heat exchanger in form of two tubes, one Inside the other with opposite massflow. I have only two fluide domaines. I have not modeled the solid part of the tube. is there a way to define in the interface the thermal resistance of the tube without having to model it?

I work with symmetries so I designed only a fourth like visible in the picture.

Thank you in advance

CFX V14.5 has option to define thin solids or add thermal resistance between interfaces. While defining interface check in " Additional Interface Models tab"
