仲氢和标准氢的黏度与热导率的研究综述OA

The thermophysical properties of hydrogen have an impact on its production,storage,and utilization.A literature survey from 1900 has been conducted on the viscosity and thermal conductivity of hydrogen,encompassing the primary measurement method,experimental research status and model development progress.The results show that current research on hydrogen transport properties suffers from problems such as immature early experimental techniques,lack of complete experimental information,and underestimated measurement uncertainty.The results of different studies in low-temperature regions vary significantly.The actual differences between parahydrogen and normal hydrogen are difficult to distinguish from measurement errors within specific temperature ranges.Constrained by the state of experimental research,the predictive performance of existing models generally decreases in low-temperature regions.Despite recent reports of new experimental and model studies,the exploration of the thermophysical properties of hydrogen at low temperatures remains insufficient.The present work analyzes the key issues in current research on hydrogen viscosity and thermal conductivity,providing a reference for future experimental measurements and model development.
