Certain metals and metal alloys can absorb hydrogen through an exothermic chemical reaction, resulting in the formation of hydrides. To maintain a rapid charging rate, produced heat must be extracted as rapidly it is generated.

Finite-volume simulations are carried out open-source software package OpenFOAM systematically investigate impacts material thermophysical properties, cooling media, exchanger design on behaviors rate. The reactor’s performance evaluated terms temperature total mass history profiles, addition pressure drop. findings indicated that time improved by roughly 86%, compared case without thermal attain 90% capacity.

Moreover, results demonstrated rate markedly effective conductivity hydride bed, increasing exchange area, accelerating lowering its temperature. outcomes highlighted possibility advancing current practical application.

Thermal lens spectrometry is a high-sensitivity method for measuring the optical and thermal parameters of samples different nature. To obtain both diffusivity absorbance-based signal measurements with high accuracy precision, it necessary to pay attention factors that influence trueness photothermal measurements. In this study, features liquid objects are studied, effects accompanying phenomena investigated. analysis dispersed solutions systems photoinduced activity associated large number side effects, impact which on not always possible determine. It take into account physicochemical properties morphological nanophase components exhibiting activity. The results obtained make reduce systematic random errors in determining thermal-diffusivity-based signals objects, also contribute deeper understanding processes sample.
