    • Abstract

       

      Considering the htermal conduction through molecular collisions an expression for the effective thermal conductivityλe of loose and granular two-phase materials at different interstitial air pressure has been derived. The dependence ofλe on pore and particle sizes, characteristic pressure and radiative heat transfer is also discussed. Calculated values ofλe of glass beads and loose building materials are compared with reported results.
