Abstract
Using some simplified models, the effective thermal conductivity of two phase media is expressed as a series-parallel combination of the individual solid and gas conductivity.
The contact point conductivity of a packed bed of sphere is presented as a function of the sphere diameter and the fraction of parallel conduction of the void is calculated as a function of porosity of the bed.
An attempt was also made to account for the contribution of the contact point conductivites with electrical analog measurements.
