Prediction of heat and mass transfer within a metal-hydrogen reactor using the unstructured Lattice Boltzmann Method

In this paper, the control-Volume Lattice Boltzmann Method (CVLBM) is adopted to solve transient heat and mass transfer in a LaNi5- H2 reactor during the desorption process. The numerical simulation was used to present the temporal evolution of the temperature and the hydrogen mass desorbed and the isotherms. In order to verify the validity of the numerical approach, the obtained results were compared firstly with those of the literature [18] and then with those of the unstructured CVFEM. We found that the CVLBM accurately predicts hydrogen desorption phenomena and has less CPU time than the CVFEM.
