Abstract
Flow and heat transfer characteristics in porous media made of copper fibers are investigated experimentally, with changing porosity and fiber size. Experimental results without heat input indicate that the flow characteristics of water coolant show almost the same tendency described by Ergun's equation. From heat transfer experiments with heat flux under 3 MW/m 2, it is clarified that the heat transfer characteristics are basically divided into four patterns by the profiles of heat transfer coefficient which also depends on the heat flux. On the basis of the obtained knowledge, it is considered that the coarsest porous medium among the ones we used is well-suited in order to remove relatively high heat input.
