Le blogue d’information En Tête de l’Université du Québec à Trois-Rivières (UQTR) présente le résumé de la thèse de doctorat en sciences de l’énergie et des matériaux de M. Siyad Ubaid, intitulée Simulation for investigatine the multiphysics performance of a cryo adsorptive hydrogen storage reservoir filles with MOF-5 for storage and distribution application. Cette soutenance a eu lieu le 21 octobre 2015.

This thesis presents the numerical study of the thermal and storage performances of a bulk adsorptive hydrogen storage reservoir filled with a metal-organic framework adsorbent material, MOF-5, for bulk storage and distribution applications. In order to investigate the multiphysics performance of the storage reservoir, at first, a general computational fluid dynamics (CFD) model is developed. The developed CFD model is validated with the experimental data obtained from the test bench equipped with a subscale-prototype (2.5 L) cryo-adsorptive tank filled with MOF-5. The validated model is extended by applying the flowthrough cooling to study its effects on the multiphysics performance of the storage system. In order to compare flowthrough simulation results with the bench test results, a series of flowthrough bench tests are performed. The original validated model is then extended to study the effect para-ortho conversion on the multiphysics performance of the storage system. Here, the model assumes that MOF-5 has enough catalytic activities for causing rapid para-ortho conversion. Finally, the CFD model that accounts for flowthrough cooling and para-ortho conversion is scaled to study the multiphysics performance of the 20 m³ bulk storage reservoir. For all CFD simulations in this thesis, COMSOL multiphysics is used as a software platform to implement the model.
