Given the thickness of the porous medium at only 2 mm, and to simplify gradient data processing, the harmonic mean of the fluid density and dynamic viscosity was utilized. Various mesh counts of wire mesh and sintered powder filler were tested. The results showed that permeability decreased for both types of fillers as mesh count increased. Due to the high randomness inherent in the sintered powder, repeated tests were conducted, with errors being within 17 %. The inertial resistance coefficient fluctuated between 300 and 600 mesh counts, with a significant increase at 700 mesh. In contrast, the inertial resistance coefficient of the wire mesh increased consistently with the mesh count. The significant inertial resistance within the sintered powder was due to its irregularity, and a high positive correlation was observed between the regularity of the filler microstructure and the pressure drop across the regenerator. The flow characteristic correlations for two types of fillers were derived, applicable within the Reynolds number ranges of 6.54 to 99.17 for the wire mesh filler and 0.86 to 15.91 for the powder filler, with both exhibiting a goodness of fit exceeding 95 % being achieved.</div></div>","PeriodicalId":14274,"journal":{"name":"International Journal of Refrigeration-revue Internationale Du Froid","volume":"169 ","pages":"Pages 362-371"},"PeriodicalIF":3.5,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, heat leakage into these cryogenic vessels leads to a continuous increase in tank pressure, potentially resulting in sudden hydrogen release and other safety concerns. While horizontal LH2 tanks demonstrate greater suitability in the transportation sector compared to vertical tanks, investigations in this domain remain scarce. Research on horizontal tanks is crucial for safe and efficient storage. Understanding these dynamics is essential for predicting temperature and pressure changes during self-pressurization, ensuring safe liquid hydrogen storage. This study designed and built a 500-liter horizontal liquid hydrogen tank for vehicle fuel storage, following ISO 13985 standards to ensure practical applicability. The project encompassed material selection, structural design, and both stress and thermodynamic analyses. Preliminary experiments were conducted using liquid nitrogen as a substitute for liquid hydrogen. Experiments assessed tank heat leakage, vapor-cooled shield insulation performance, thermal stratification, lossless storage time, and pressure changes during self-pressurization and steady-state evaporation. Results validate the efficiency of our pressure vessel design method for complex conditions, enhancing understanding of self-pressurization and thermal stratification in horizontal tanks. The vapor-cooled shield reduced heat leakage into the tank by 22.7%, decreasing the daily evaporation rate under liquid nitrogen conditions from 1.87 wt% to 1.5 wt%. and maintaining an initial liquid level of 50% extended the lossless storage time to 50 h in the LN2 scenario.
