Abstract:
The task of determining the Kapitza conductance through an interface between two solid bodies considering the roughness of the interface is formulated and solved for the first time. A modified acoustic mismatch model (AMM) is used. The difference from the standard model consists in the fact that the disperse properties of acoustic waves are taken into account. A substantial advantage of this model is the fact that its predictions are in agreement with the data in a wide range of temperatures from 30 to over 300 K. Eventually, it is very important that a method considering the statistical distribution of the roughness profiles is used for the determination of the energy transfer coefficient through the interface for the first time.
