Abstract
The procedure of volume averaging is applied to the process of steady- stale heat conduction in a two-phase system and a method is developed to calculate the effective thermal conductivity. This method provides details of solid mechanics and thermal problems, and particle-particle contact is treated in an empirical manner. The proposed method is app lied for periodic regular arrangements of circular and square cylinder s. The effects of particle shape, roughness and solid conductivity are examined. A qualitative comparison between theory and experiment is a lso reported. Copyright (C) 1996 Elsevier Science Ltd.
