Optimized the Internal Fins Arrangement in Metal Hydride Container by Minimum Entropy Generation / 以最小熵增定理探討金屬儲氫罐內溫控鰭片優化分析

碩士 / 逢甲大學 / 機械與電腦輔助工程學系 / 101 / This thesis analyzed and discussed the metal hydride hydrogen storage heat and mass transfer in the tank, which equipped fined heat tube. After several validations, the mathematical models and numerical methods constructed in this study could accurately simulate the experimental results. Besides, in order to comprehend how various parameters within fined heat control system effect metal hydride hydrogen storage, hence we compared the initial hydrogen pressure, temperature and flow rate to figure out the influences of hydrogen storage efficiency. By contrasting to changes of temperature and density field in different stages, we could understand the physical phenomena during hydriding process, then use minimum entropy method to discuss how flow rates and fins impacted on the heat transfer entropy and friction entropy generation. The numerical results showed that increased flow rates could enhance heat transfer efficiency and reduce heat transfer entropy generation but friction entropy generation of fluid increased exponentially with growth flow rate. Overall, the numerical results in this study could be a reference of designing metal hydride hydrogen storage tank in the future.
