Abstract
In the current work, a parametric numerical analysis of MmNi4.6Al0.4 is studied during the hydrogenation process; under effective heat management. A fully validated with solid experimental results mathematical model including the heat, mass and momentum conservation equations is introduced, described and incorporated on a Multiphysics software (COMSOL Multiphysics). The target of the current study was the storage of 200g of hydrogen per hydrogenation/dehydrogenation cycle within 5000s. The heat management during the hydrogenation process was performed by the usage of plain-embedded cooling tubes in combination with extended surfaces. The parameters examined in the current work were; the fin thickness, the fin number (metal hydride thickness) and the coolants’ flowrate within the tubes. A
non-dimensional parameter was utilised for the evaluation of the heat management process. The results showed that the optimum fin number was 60, in combination with fin thickness 5-8mm and the value of the heat transfer coefficient 2000-5000 Wm-2K-1.
