삼중수소 저장을 위한 ZrCo 저장재에서의 수소 흡장에 대한 수치해석적 연구 (I) = A Numerical Investigation of Hydrogen Absorption Reaction Based on ZrCo for Tritium Storage (I)

다국어 초록 (Multilingual Abstract)

In this paper, a three-dimensional hydrogen absorption model is applied to a thin double-layered annulus ZrCo hydride bed and validated against the temperature evolution data measured by Kang et al.1) The present model reasonably captures the bed temperature evolution behavior and the 99% hydrogen charging time.
The equilibrium pressure expression for hydrogen absorption on ZrCo is derived as a function of temperature and the H/M atomic ratio based on the pressure-composition isotherm data given by Konishi et al.2) In addition, this present model provides multi-dimensional contours such as temperature and H/M atomic ratio in the thin doublelayered annulus metal hydride region. This numerical study provides fundamental understanding during hydrogen absorption process and indicates that efficient design of the metal hydride bed is critical to achieve rapid hydrogen charging performance. The present three-dimensional hydrogen absorption model is a useful tool for the optimization of bed design and operating conditions.
