Optimization study on hydrogen absorption performance of metal hydride hydrogen storage reactor based on cylindrical heat exchanger
摘要
Abstract
In this study,a multi-physical field coupling model of metal hydride hydrogen storage reactor(MHHSR)based on cylindrical heat exchanger was established.The influence of the geometric shape and position of the cylindrical heat exchanger on the hydrogen absorption performance of the reactor was investigated,and the mathematical model was developed.The optimal position of the heat transfer structure was obtained,and the characteristics and intrinsic mechanisms of heat and mass transfer in the alloy bed during the hydrogen absorption process were explored.Additionally,based on the area of the temperature differential zones among different layers,the uniformity of heat transfer in multi-layer beds was analyzed.The research results showed that when the embedded heat transfer ring was located at 0.62R of the alloy bed,the hydrogen storage reactor achieved 90%hydrogen capacity within the shortest time.By comparison to the central heat exchange tube structure and the external heat exchange jacket structure,there was a time reduction of 76.3%and 60.7%,respectively.Different types of heat exchanger structures caused differences in the thermal mass transfer characteristics of the alloy bed,which changed the evolution modes of the bed,s reaction interface area and moving speed,ultimately affecting the reactor,s hydrogen absorption performance.When multiple independent reaction bed layers existed in the reactor,a smaller temperature difference region area among different bed layers resulted in more uniform heat and mass transfer and higher energy efficiency of heat exchanger structures.关键词
