Modelling of the conductive heat transfer through nano-structured porous silica materials

► Development of a numerical model for conductive transfer in nanostructured silica. ► Takes into account the realistic morphology at nanometric and microscopic scales. ► Resolves the Boltzmann equation since macroscopic laws are questionable. ► Computations conducted using phonon properties of silica obtained in literature. ► Influence of structural characteristics and thermo-physical properties analysed.
