Numerical modeling and performance evaluation of multi-tubular sodium alanate hydride finned reactor

Modeling of cooling system for hydrogen storage process with sodium alanate and catalyzed by titanium chloride

“…Within these compounds, the anhydrides of sodium, lithium, boron and beryllium are much more used due to its storage capacity and operative conditions such as temperature and pressure [20]. By the same reason alanates, amides, imides and borohydrides are interesting complex hydrides because of its high content of hydrogen and low weight.…”

A novel multilayer fin structure for heat transfer enhancement in hydride-based hydrogen storage reactor

“…Bhouri et al assembled 7 tubular reactors with a tube‐fin heat exchanger into a shell. To investigate the influence of operating parameters and fin radial length, analytical and numerical models were established . However, we note that the detailed fin geometry, say, the profile, which may substantially affect the cost and overall heat transfer of the reactor, is paid little attention in existing studies.…”

“…To investigate the influence of operating parameters and fin radial length, analytical and numerical models were established. 33 However, we note that the detailed fin geometry, say, the profile, which may substantially affect the cost and overall heat transfer of the reactor, is paid little attention in existing studies. Moreover, the fundamental analysis based on heat transfer theory toward optimization of such tube-fin reactor is lacking.…”

A generic physical model for a thermally integrated high-temperature PEM fuel cell and sodium alanate tank system

“…As such, the material can no longer absorb more hydrogen resulting in incomplete fillings. The design of efficient cooling systems for MH tanks is thus a crucial factor in order to take advantage of the maximum storage capacity of the material [3]. Hydrogen desorption, on the other hand, is an endothermic reaction that requires sufficient heat fluxes to be provided to the MH tank in order to maintain the desired desorption mass fluxes needed to run a FC.…”

“…For higher temperature applications though, using e.g. HT-PEMFCs, where the humidified exhaust gases act as a strong oxidizing agent for the metal parts of the integrated system, thermal liquids can be used instead for more efficient heat transfer [3].…”
