The procedure of volume averaging is applied to the process of steady-state heat conduction in a two-phase system and a method is developed to calculate the effectivethermalconductivity. This method provides details of solid mechanics and thermal problems, and particle-particle contact is treated in an empirical manner. The proposed method is applied for periodic regular arrangements of circular and square cylinders. The effects of particle shape, roughness and solid conductivity are examined.

Abstract
The procedure of volume averaging is applied to the process of steady-state heat conduction in a two-phase system and a method is developed to calculate the effectivethermalconductivity. This method provides details of solid mechanics and thermal problems, and particle-particle contact is treated in an empirical manner. The proposed method is applied for periodic regular arrangements of circular and square cylinders. The effects of particle shape, roughness and solid conductivity are examined. A qualitative comparison between theory and experiment is also reported.File in questo prodotto:
