【 摘 要 】

References(12)Cited-By(2)Metal hydride (MH) attracts considerable attention for not only hydrogen storage devices but also chemical heat pumps (CHPs). Many previous researchers pointed out low effective thermal conductivity of MH packed bed resulted in low performance. Indeed, several attempts have been done to improve it. However, no guideline for improving the thermal performance with heat transfer enhancement has been discussed. In this study, thermal performance for a packed bed reactor of MH is numerically investigated. Diagrams for the heat transfer enhancement are developed according to the numerical results. The previous strategies to improve effective thermal conductivity can be combined with the diagrams for the practical use.
