Representation of thermal conductivity of solid material with particulate inclusion

This paper reviewed the previously proposed models of thermal conductivity (κ) for a series and parallel flow of energy input in laminated composites. These two models were coupled to derive the thermal conductivity (κa) of material with simple cubic particulate inclusion. The derived equation depends upon κ1 of inclusion, κ2 of a continuous phase and volume fraction of inclusion. The size and shape factors of inclusion are cancelled during the derivation of κa. The newly constructed κa equation explains well the measured κa for AlN particle-dispersed SiO2 system.
