Dynamic behaviour of simple hydride bed devices

Influence of aluminium content on the dynamic characterstics of mischmetal based hydrogen storage alloys

“…However, the values obtained from the slopes of the above graphs are termed as "apparent" reaction enthalpy and "apparent" reaction entropy as suggested by Goodell et al [10]. The dynamic PCIs and the ln(P e ) versus 1/T graphs give more accurate prediction of the dynamic behaviour and the operating characteristics of hydride bed devices than can be obtained from the static PCIs and van't Hoff plots [11]. The slope increased with increase in Al content.…”

Metal hydrides for energy applications - classification, PCI characterisation and simulation

“…However, the PCI obtained from dynamic method does not represent the equilibrium conditions, but the data obtained closely represents the practical conditions. Additionally, for simulation of thermodynamic devices, van't Hoff plots obtained from dynamic PCI gives more realistic results .…”

Prediction of Metal Hydride Heat Transformer Performance Based on Heat Transfer and Reaction Kinetics

“…Few experimental studies have been carried out on the dynamic aspects of paired metal hydrides. Tuscher et al (1984), Anevi et al (1984), Nagel et al (1986a,b), and Bjurstrom et al (1987) have carried out studies on dynamic aspects 0888-5885/95/2634-2305$09.00/0 of single and paired metal hydride systems. These studies show that sorption kinetics and heat transfer processes in both the reactors are coupled, and together they determine the rate of hydrogen transfer between the two hydrides.…”
