A methodology is introduced for predicting the effective thermal conductivity of arbitrary particulate composites with interfacial thermal resistance in terms of an effective medium approach combined with the essential concept of Kapitza thermal contact resistance. Results of the present model are compared to existing models and available experimental results. The proposed approach rediscovers the existing theoretical results for simple limiting cases. The comparisons between the predicted and experimental results of particulate diamond reinforced ZnS matrix and cordierite matrix composites and the particulate SiC reinforced Al matrix composite show good agreement. Numerical calculations of these different sets of composites show very interesting predictions concerning the effects of the particle shape and size and the interfacial thermal resistance.read more

Thermal boundary resistance
E. T. Swartz,Robert O. Pohl +1 more
TL;DR: In this article, the thermal boundary resistance at interfaces between helium and solids (Kapitza resistance) and thermal boundary resistances at interfaces interfaces between two solids are discussed for temperatures above 0.1 K. The apparent qualitative differences in the behavior of the boundary resistance in these two types of interfaces can be understood within the context of two limiting models of boundary resistance, the acoustic mismatch model, which assumes no scattering, and the diffuse mismatch model that all phonons incident on the interface will scatter.
