Abstract

The present studies in literature related to modelling and/or predicting effective thermal conductivities of porous mediums have been reviewed in detail. These studies have been analysed by using some experimental results, including different applications and found in literature. The results are given in Tables, and these models are evaluated in terms of the effects different parameters, applicability interval, and usage convenience. It is concluded that, instead of obtaining relations which can be used generally, choosing of matematical relations to use with finite errors for specific structures and in specific porosity intervals has become important, and particularly, it is concluded that the effect of high temperature on the effective thermal conductivity needs to be studied.
