多孔質金属フィンを用いた蓄熱促進

Effects of orientation direction, Darcy number and Rayleigh number of the porous metal fins installed in a rectangular enclosure on the solidification process are investigated by dimensionless numerical analysis. Specifically, the thermal storage capacity in PCM and the time to complete solidification are examined in this paper. Comparing the three cases of porous metal fins, full porous, and only PCM, we confirmed that porous metal fins have an advantage in thermal storage. Especially in the early stage of solidification with porous metal fins, cold heat is used for sensible heat rather than latent heat because of convective flow.
