  SYMMETRY AND ASYMMETRY MODEL FOR THERMAL CONDUCTIVITY IN POROUS MEDIA

  By Carlos Armenta-Deu, Leticia Bottazzi

  Abstract: This paper focuses on determining thermal conductivity in porous media using symmetry and asymmetry models. Since porous media are not uniform and homogeneous in most of the cases, anisotropy must be taken into account, what derives in the application of an asymmetry model as thermal gradients are not equal in all directions. The paper demonstrates that, under certain conditions, isotropic conditions, therefore, symmetry model can be applied to non-homogeneous or …

  VARIATION OF THERMAL CONDUCTIVITY WITH POROSITY

  By Carlos Armenta-Deu, Leticia Bottazzi

  Abstract: Thermal conductivity in porous media as a function of the grain size and porosity has been studied establishing a relation between these two parameters. The study has been developed for a homogeneous porous medium with grain size in a very close range of particle diameter. The study has been extended from very small particles to large ones, to cover most of the real grain size. As a result of this …
