Effective Thermal Conductivity of Functionally Graded Particulate Nanocomposites With Interfacial Thermal Resistance
TLDR
In this article, a self-consistent model was proposed to investigate the effective thermal conductivity distribution in a functionally graded particulate nanocomposite, where the Kapitza thermal resistance along the interface between a particle and the matrix was simulated with a perfect interface but a lower thermal conductivities of the particle.Abstract:
By means of a fundamental solution for a single inhomogeneity embedded in a functionally graded material matrix, a self-consistent model is proposed to investigate the effective thermal conductivity distribution in a functionally graded particulate nanocomposite. The "Kapitza thermal resistance " along the interface between a particle and the matrix is simulated with a perfect interface but a lower thermal conductivity of the particle. The results indicate that the effective thermal conductivity distribution greatly depends on Kapitza thermal resistance, particle size, and degree of material gradient.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.
