Heat Transfer after Deformation (Contact Pair)

Hi,

i am trying to model heat transfer between two concentric cylinders where inner one is heated.
The inner cylinder is pressurized and eventually touches the outer one.

For modeling structural phenomena i am using "contact pair".

What do i need to do for heat transfer so that as the contact takes place and contact area increases, there is heat transfer from inner cylinder to outer one.


Could you plz help?
