Effect of included media on thermal conductance of contact joints.
Abstract
Whenever an engineer turns to the available literature for
information concerning heat flow across a joint formed by two
pieces of material in simple contact, he is apt to read a phrase
similar to this, The resistance to the flow of heat between two solid surfaces
in simple mechanical contact is highly unpredictable. Thus the problem of thermal contact resistance which has concerned
engineers for a century or more continues to be important in conventional
design and may be the critical design factor in nuclear
power work where extremely high heat fluxes are encountered. Yet,
as Dr. Glasstone implies, much information remains still uncovered
concerning heat flow across such an interface.
