Hi,

I am solving fluid flow and heat transfer in a double pipe counter flow heat exchanger filled with porous media (see the domain in attached picture ). I need to apply a boundary condition to ensure continuity of energy and temperature at the wall-fluid-solid interface. The inner pipe wall thickness is required to be modelled as well. I am facing difficulty understanding how such a boundary condition( see attached picture) can be applied in Fluent.

Any suggestions regarding approach or UDF will be very helpful. Radiation can be neglected.

Thanks in advance.
