Effective thermal conductivity model of particle-filled composite materials with distributed inner heat sources.

ABSTRACT: Effective thermal conductivity (ETC) of composite materials is an important lumped parameter to describe heat conductions inside composite materials without dealing with complex structures. When particles release heat inside composite materials, like particle-filled nuclear fuel elements, classical ETC models are not appropriate and the effect of inner heat source requires further investigation. In our previous researches, heat conductions with inner heat sources were analyzed and the ETCs were redefined to predict the average temperatures of composite materials. Current work continued to study the ETC model of spherical composite materials with distributed heat-releasing particles. In the spherical two-phase composite material, a number of identical particles were dispersed in the matrix
