Modelling of effective thermal conductivity for a nonhomogeneous anisotropic porous medium (Q1287866)

Based on the microscale temperature, we evaluate the effective thermal conductivity in the principal direction of an anisotropic porous medium. A correlation of the effective thermal conductivity then is employed to predict the volume-averaged temperature of a two-dimensional nonhomogeneous anisotropic porous medium. Through an example, the present model is found to possess an excellent performance even when the principal direction of the anisotropic medium is not parallel to the physical coordinates.
