A novel effective medium theory for modelling the thermal conductivity of porous materials

Cumulative pore volume, pore size distribution and phases percolation in porous inorganic polymer composites: Relation microstructure and effective thermal conductivity

“…Combing these additions with the Water/metakaolin ratio, our objectives were to present optimum parameters for the development of better expanded structures with pore shape and pore size distribution achieved for a better description of the porous structure by existing analytical models available in the literature like Maxwell-Eucken model [4,6] and the novel effective medium theory proposed recently [13,14].…”

“…The first basic consideration for the analytical description of the thermal conductivity of porous materials have being the description of the matrix as two-phase system: a skeleton and air [13][14].…”

“…A novel effective medium theory for modeling the thermal conductivity of porous materials proposed by Gong and al [13][14] consider the basic structural models including the series, parallel,…”

“…It is postulated that phases in porous materials are small spheres dispersed into an assumed uniform structure (two-phases) with thermal conductivity K m [13][14]. For porous geopolymers under study, their model can be written as (11): )…”

Thermal and hydraulic performances of a tube filled with various thermal conductivities of porous media

“…He validated his model by conducting an experimental study and claimed that the collected data and results are in good agreement. Gong et al [29] introduced a novel theory to model the thermal conductivity of a porous medium. It is assumed that phases are small-scale spherical particles spread into a homogenous medium with a finite thermal conductivity coefficient.…”
