The current study uses a corrugated cooling channel with ternary nanofluid to present an innovative thermal management strategy for metal hydride–hydrogen storage. Using a finite element approach, numerical simulations are carried out for Reynolds numbers (Re) ranging from 2.5 to 100. For both base fluid and nanofluid employed as the coolant in the cooling channel of storage system, the effects of varying corrugation amplitude and wave number on performance are investigated. Considering the lowest and higher Re configurations, heat transfer enhancement factors become 4.6 and 4.2 for base fluid and nanofluid cases. However, varying amplitude and wave number lead to 32%, and 9.8% improvement in the cooling performance of the channel when used with nanofluid. Dynamics of the bed temperature and hydrogen content in the metal hydride are affected most by varying flow Re, and fluid type while corrugation amplitude is effective when used with higher Re. Due to the enhanced cooling process, the storage system maintains approximately 33% of improvement with the highest concentration by using a higher nanofluid velocity. When adopting corrugated channels, both base fluid and nanofluid exhibit better storage performance at t=300. In comparison to the flat case, the corrugated channel case shows a 12% increase in storage. Even with a flat channel configuration, the absorbed hydrogen concentration of the metal-hydride bed reaches its maximum for nanofluid at t=1000 s. The results of the current study can be used to develop alternative cooling systems and optimize efficient cooling solutions for hydrogen storage in metal hydrides.</div></div>","PeriodicalId":23062,"journal":{"name":"Thermal Science and Engineering Progress","volume":"65 ","pages":"Article 103817"},"PeriodicalIF":5.1,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144656832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functionally graded materials (FGMs) are a unique class of composites with gradually varying properties along their dimensions, typically achieved by specific distribution patterns of reinforcements within a matrix to create a desired gradient in properties. This study presents a novel numerical modeling method for analyzing heat conduction in composites and FGMs. The approach utilizes the finite element method combined with an embedding technique, allowing for the integration of fiber- and/or particle-based reinforcements within a matrix. The proposed method allows uncoupled meshes between the distinct phases, enhancing the adaptability of the model. Our results show that this embedding technique is capable of integrating heterogeneous elements within the domain without increasing the degrees of freedom, while effectively capturing local effects. The maximum mean relative error found was 7.25%. We showed that the errors depend on the complexity of the problem and lower errors can be obtained with finer discretizations.

To elucidate the underlying mechanism through which metal elements affect the spontaneous combustion process of coal when exposed to UV irradiation, four metal compounds were chosen as reactants and thoroughly mixed with coal samples. The effects of metal ions on the spontaneous combustion characteristics of coal before and after UV exposure were analyzed using temperature-programmed experiments, thermogravimetric-differential scanning calorimetry (TG-DSC), and in-situ Fourier transform infrared spectroscopy (in-situ FTIR). The results indicate that metal ions promote the spontaneous combustion of coal in the absence of UV irradiation, while their effect shifts to inhibition after UV exposure. Under UV irradiation, the apparent activation energy of the mixed coal samples increased at different stages of low-temperature oxidation, particularly during stage II, with a maximum increase of 7.81 kJ/mol. Compared to raw coal and mixed coal samples without UV irradiation, the characteristic temperatures of the UV-exposed mixed coal samples generally increased, while heat release significantly decreased. Notably, Cu<sup>2+</sup>-treated coal showed the most significant temperature increase (29.2–114.5 °C) and the lowest combustion index. Further analysis showed that the easily oxidized side chains and bridge bonds in coal samples were broken after UV irradiation, and humic acid fell off from coal macromolecules, resulting in an increase in humic acid content.

The key parameters evaluated include exit flue gas temperature, maximum system working pressure, and gas turbine efficiency. A multi-objective optimization framework was applied, and the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method was used to determine optimal operating conditions, considering thermal efficiency, compressed gas mass flow, and total system cost.

Coaxial nozzle geometry, the dimensionless nozzle-to-plate distance (<em>H/D</em> = 0.8–3.2), fin length (0, 2, and 6 mm), flow rate ratio (<em>Q*</em>=0.176–0.823) and restricted and unrestricted jet depending on the presence or absence of blocking plate are taken into consideration as parameters and states.
