Interface conductance modeling

masb · April 18, 2014, 17:58

Dear all,

I'm looking for some approach to model interface heat conductance within OpenFOAM context. It refers to the ease with which heat can be transferred across an interface between two surfaces which are in contact. Any help is appreciated.

Thanks,

Marco.

There is no support for contact resistance the easiest way to do it is by inserting a thin region of elements and adjust the conductivity of these elements to give the correct contact resistance.

if you found any other method to do please let me know
