Inserting rotation introduces novel mechanisms that can enhance heat transfer and optimize the overall performance of LHES systems. The shell and tube system are used as LHTES. Varying the rotational speed has an important role in the charging process, but there is an inconsistency related to the impact of changing the rotation speeds on melting time. This study provides a systematic and comprehensive approach to addressing the discrepancies found in previous research regarding the relationship between rotational speed and melting time. It fills the research gap by conducting a detailed analysis of a specific range of rotational speeds (0.1–3 rpm). Additionally, it highlights the gradual influence of rotation, starting with a negligible effect in the initial phases and evolving into a crucial factor in enhancing melting once a certain liquid fraction is reached—an aspect not previously explored in the literature. Seven main cases have been defined with different rotational speeds to choose the best case that would result in the shortest complete charging time. The results indicated that increasing the rotation speeds from 0.1 to 1 rpm and 3 rpm shortened the charging time by 41% and 47%, respectively. Also, it is found that the positive influence of rotation starts at 0.51% of liquid fraction.</p>\u0000 </div>","PeriodicalId":44939,"journal":{"name":"Heat Transfer","volume":"54 5","pages":"3001-3014"},"PeriodicalIF":2.8,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to investigate the potential heat transfer enhancement by combining the influence of cavity inclination angle and twin fin orientation for an air-filled cavity. The SIMPLE algorithm is used to solve the governing conservation equations, which are discretized using the finite volume method. The thermal field and internal fluid flow are calculated for a range of Rayleigh numbers (10⁴ ≤ Ra ≤ 5 × 10⁵), cavity inclination angle (0° ≤ φ ≤ 60°), fin orientation (−60° ≤ <i>γ_a</i> and <i>γ_b</i> ≤ 60°), and fin positions (0.375 ≤ <i>L_a</i> ≤ 0.75, 0.25 ≤ <i>L_b</i> ≤ 0.625). Outcomes indicate that increasing Rayleigh number leads to enhancement in the intensity of the internal fluid flow in the cavity. Furthermore, the heat transfer rate is enhanced by positively orienting fins for the optimal cavity inclination angle φ = 15°. Moreover, installing the plate fins on the upper part of the left hot sidewall improves the heat transfer characteristics. Combining fin orientation and cavity inclination shows potential heat transfer enhancement, which achieves its maximum for a cavity inclination φ = 15° and twin fins with positive orientations of <i>γ_a</i> = <i>γ_b</i> = 60°. The heat transfer is enhanced by up to 15.32% compared to the reference case.

In this study, a liquid desiccant dehumidification system combined with a VCR-based air conditioning system (LDVC) with a cooling capacity of 5 kW was experimentally investigated using calcium chloride as a liquid desiccant solution. An uncertainty analysis was conducted to ensure the sensitivity and accuracy of the obtained results. For the investigation, three factors, airflow rate, desiccant flow rate, and desiccant concentration, with four input levels, were selected. Various combinations of these factors and levels used the Taguchi method to determine their effects on relative humidity difference, absorber heat load, coefficient of performance of the LDVC, and energy savings. Regression corrections for all responses were also determined. The performance of the LDVC was compared with that of a standalone VCR system under identical input conditions and cooling effects. Based on the TOPSIS results, the experimental outcomes achieved a reduction in specific humidity by 9.8 g/kg of dry air, an absorbed heat load of 1.23 kW, a COP of 2.23, and an energy saving of 49%. Compared to the standalone VCR system, the COP increased by 26%, with the dehumidifier sharing 49% of the latent heat load. Exergy analysis revealed that the compressor and absorber exhibited low exergy efficiency, highlighting the potential for performance improvement. Economic analysis indicated a payback period of 3.6 years.

Such challenges impose reducing greenhouse gas emissions, increasing renewable energy storage rates, meeting the perishable food needs for cooling, and mitigating food wastage through power outages. While previous investigations contributed to these goals by studying the potential benefits of adding phase change materials (PCMs) to DRSs, our study extends their application to chest freezers: a type of system still underexplored. Additionally, it seeks to enhance industrialization and design decision-making towards tailoring different solutions to distinct markets. Namely, by adopting test procedures closely adhering to the European Standard EN 62552:2013 for experimentally testing four prototypes. The analysis of the novel systems' performance focuses on two metrics internationally recognized but scientifically overlooked by previous peer research: the temperature rise time and the daily energy consumption. A novel approach for filling the top-mounted door with PCMs and an industrialization technique for simultaneous wrapping PCM bags and evaporator tubes around the freezer compartment are introduced to incorporate PCMs, with melting temperatures (<i>T</i>_m) of −21°C and −12°C. Our findings reveal the potential to extend blackout autonomy by 7%–40% and to reduce daily energy consumption by 13%. Furthermore, the results demonstrate that higher <i>T</i>_m values enhance the commercial attractiveness of DRSs in regions with unstable electricity grids where significant autonomy gains are appreciated, while lower <i>T</i>_m values suit sophisticated markets where extended energy storage capacity and compressor lifetime can be prioritized.</p>\u0000 </div>","PeriodicalId":44939,"journal":{"name":"Heat Transfer","volume":"54 4","pages":"2933-2954"},"PeriodicalIF":2.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
