Effect of Boundary Conditions on the Hydrogen Absorption in a Metal Hydride Reactor

In this paper, a numerical study of the heat and mass transfer in a metal hydride reactor is presented. The reaction within the metal hydride reactor is exothermic. That makes the hydriding process less effective. Thus, a cooling system is needed to reduce the temperature in order to increase the amount of the absorbed hydrogen. The geometry of the studied reactor is cylindrical with (H=3cm) of height and (R=5cm) of radius. A heat exchanger is considered in the lateral and base walls. The transfer is considered two-dimensional and transient. The governing equations of the transfer phenomenon are based on the conservation principle of mass, momentum and energy. Using the finite volume method…
