Contact thermal resistance
Model of Rough Contacts using a Statistical Approach

In mechanisms, assemblies are primarily designed to transmit forces, and this aspect has been detailed in the preceding paragraphs. However, assemblies can also be used to transmit heat, and different types of problems can arise when analyzing heat transfer in a static assembly. For example, an assembly may be subjected to a thermal gradient, in which case we need to know the flow transmitted by the stack. Alternatively, the stack may be subjected to an imposed flow, in which case we need to determine the temperature maps. In either case, conduction laws combined with resolution methods widely developed at [BE8200]...
