Abstract: Turbulence mixing in T-junctions filled with porous metal materials is numerical investigated using Large-eddy simulation turbulence model. Three cases of porous metal materials, made of three sintered metal spheres with different thermal conductivities (387.6 W/m۟۬•K for copper, 202.4 W/m۟۬•K for aluminum and 16.3 W/m۟۬•K for steel), are predicted. Compared the results of three cases, a higher thermal conductivity can also contribute more greatly to heat transfer enhancement. In T-junctions filled with porous metal materials, thermal conductivity is weakened considerably by the turbulence mixing of hot and cold fluid. The temperature fluctuation are no obvious different.

Abstract: Porous metal materials have been widely used in various industrial fields in the world. This paper describes the recent research achievements of CISRI in the development of porous metal materials. High performance porous metal materials, such as large dimensional and structure complicated porous metal aeration cones and tube, sub-micron asymmetric composite porous metal, metallic membrane, metallic catalytic filter elements, lotus-type porous materials, etc, have been developed.
