Perforation Effect on a Rectangular Metal Hydride Tank for the Hydriding and Dehydriding Process by Using COMSOL Multiphysics Software

In this paper, a 3 Dimensional dynamic model of a perforated rectangular metal hydride tank is presented. The metal hydride tank consists of powder LaNi5 and the tubes are organized in the geometry of the rectangular in order to simulate the flux of the ambient air through the reactor, which affect hardly both the hydriding and the dehydriding reaction. A simulating study is made by solving simultaneously the energy, mass and momentum differential equations of conservation by using Comsol Multiphysics (version 4.2) software. The simulation results show great agreement with the experimental data.
