抄録

Effective thermal conductivity and permeability of a porous medium were examined as a function of porous diameter at constant porosity. If the porous diameter increases at constant porosity, the number of pore should reduce and as the result the contact area to solid material also decreases. Effect of solid material becomes large and effective thermal conductivity increases. This tendency was experimentally confirmed by using three kinds of ceramic material (porous diameter d_f=1.3mm, 2.0mm and 4.2 mm, porosity &epsilon = 87%). In addition, permeability was determined experimentally for various porous diameters by using Ergun's equation including viscous term and kinetic term.
