The introduction of dropwise condensation (DWC) within the heat pipe is a promising way to further enhance the thermal performance significantly. However, the departure of unique discrete condensing droplets highly depends on the orientation and the dynamic wettability of condensing surfaces, which brings new challenges to the DWC enhanced heat pipe technologies. In this work, a condensation surface with periodic superhydrophilic grooves and hydrophobic ridges was proposed to address the orientation dependency of the DWC inside the heat pipe. A visualization experimental system for flat heat pipes was developed to investigate the phase change dynamics and the thermal performance. Results indicate that the periodic superhydrophilic grooves optimize the sizes of condensing droplets. Under the Laplace pressure induced by the wettability difference, the condensing droplets are rapidly removed by the superhydrophilic grooves, achieving a 62% reduction in condensation thermal resistance compared to conventional heat pipes at 0°. Compared to the uniform hydrophobic surface, the droplet departure radius and growth cycle time on the hybrid wettability grooved surface were reduced by 51.9% and 10.6%, respectively, at 90°. The corresponding condensation thermal resistance and evaporation thermal resistance of the hybrid wettability grooved surface were reduced by 45% and 17%, respectively, compared to those of the conventional grooved surface. Furthermore, the effective thermal conductivity of the proposed heat pipe was enhanced by 117.5% and 54% at inclination angles of 0° and 90°, respectively, compared to the conventional grooved heat pipe at 60 W. The optimal filling ratio for the proposed heat pipe is revealed to be 18%-25% at an inclination angle of 90° and 42% at an inclination angle of 0°. This work demonstrates promising solutions in enhancing the current thermal performance of heat pipes with and without the assistance of gravity, providing new guidance for advancing DWC enhancement within the closed two-phase devices.</div></div>","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"352 ","pages":"Article 121141"},"PeriodicalIF":10.9,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146075358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a hydrogen-integrated net-zero energy district framework that couples passive building design strategies, active energy systems, and water reuse measures with a district-scale hydrogen energy hub. Using a developed open-source hydrogen simulation model (H₂UrbanPlus), a newly planned district of 22 residential buildings is simulated under five design scenarios combining photovoltaics, passive shading, green roofs, and hydrogen-based storage. Results show that hydrogen plays a pivotal role in enabling seasonal balancing and resilience: district self-sufficiency rises by up to 85.6%, annual carbon dioxide emissions are reduced by 159 tonnes annually, and the system achieves near-carbon neutrality. Techno-economic evaluation demonstrates that hydrogen integration, when coupled with urban passive and water-energy synergies, lowers the effective levelized cost of electricity and improves the net present value of district investments. By providing a first district-scale co-simulation of passive, active, hydrogen, and water-recovery systems in a semi-arid hot-climate context, this study delivers new quantitative evidence on the role of hydrogen-enabled energy hubs in supporting resilient, low-carbon, and self-sufficient urban districts, offering actionable insights for planners and policymakers shaping future net-zero and hydrogen-transition strategies.</div></div>","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"352 ","pages":"Article 121088"},"PeriodicalIF":10.9,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146075291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system combines high energy storage density (EVR) with high round-trip efficiency (RTE), showing promising prospects for future energy management and system integration. LCES systems typically face challenges related to low condensation efficiency and incomplete working fluid liquefaction. To address these issues, the proposed LNG-LCES-ORCE system integrates external LNG cold energy, a two-stage Organic Rankine Cycle (TS-ORC) subsystem, and a cold energy storage subsystem (CESS). It innovatively employs a mixed working fluid approach to simultaneously enhance CO₂ liquefaction efficiency on both low- and high-pressure sides. The CESS configuration enables the overall system to flexibly and efficiently utilize cold energy throughout the day. Comprehensive analyses of system performance and economic viability were conducted through mathematical and economic modeling. Additionally, exergy analysis identified components requiring improvement. Finally, a multi-objective optimization using a genetic algorithm was performed to achieve optimal system performance. The results indicate that the proposed system attains an Overall-System-RTE of 92.047%, an EVR of 12.221 kWh/m³, and a levelized cost of electricity (LCOS) of 0.1018$/kWh. Compared to other LCES systems, the LNG-LCES-ORCE system demonstrates superior performance and economic benefits. It should be noted that the LNG cold energy is treated as an externally available resource in this study.

The diffusion flame combustion behavior of blended fuel at low pressure—as a pioneering research problem—involves complex interactions of various flows, liquid–vapor phase transitions, heat-mass transfer processes and multi-component chemical reactions. This work investigates key characteristics of n-Heptane/DGM blended fuel pool fire with a lip height, including flame color, burning rate, flame height and temperature distribution under various ambient pressures (40 kPa–101 kPa). A distinct vapor-rich zone near flame base is observed for pool fire with a lip height, particularly at relatively low ambient pressures. The bluish flame base sheet extends more significantly under low-pressure conditions; a theoretical relation between oxygen entrainment and ambient pressure is deduced. A new correlation has been established relating flame height to both ambient pressure and combustion heat of blended fuel. By analyzing energy equation, the temperature distribution characteristics of flame development region were examined in detail, and exhibits a linear relationship with height. A theoretical model based on the Peclet number (<em>Pe</em>) is proposed to characterize this temperature gradient, which is intensified by the restricted air entrainment under low-pressure conditions. This study utilizes comprehensive experimental data and theoretical models to advance understanding of blended fuel diffusion flame structure under low pressure.

In PCM-based thermal management systems, the discharge cycle is just as important as the charging cycle, but it is often not studied enough. This work experimentally investigates in detail four different configurations of a heat sink (HS) with a phase change material (PCM): (i) a PCM-filled heat sink (PHS), (ii) a PCM-filled finned heat sink (PFHS), (iii) a PCM-filled finned heat sink integrated with a heat pipe (PFHSHP), and (iv) a PCM-filled finned heat sink coupled with a finned heat pipe (PFHSFHP). Docosane is the selected phase change material, and the tests are carried out at different power inputs (6, 8, 10, and 12 W) and controlled surrounding temperatures (24, 26, and 28 °C). The findings reveal that thermal performance depends to a large extent on the configuration and ambient conditions, and better performance is achieved at surrounding temperature of 24 °C. Among the investigated designs, the PFHSFHP configuration consistently exhibits the best charging and discharging performance across all operating conditions. For example, at an 8 W power level and S_T = 28 °C, the percentage improvement in charging time in PFHSFHP compared to PHS, PFHS, and PFHSHP is 35.49 %, 34.06 %, and 27.54 % respectively. Under the same conditions, the percentage reduction in discharging time is 30.94 %, 18.78 %, and 11.99 % respectively. The performance increase is mainly due to better heat spreading and faster heat rejection, which were made possible by the finned condenser section of the heat pipe, which maintained a higher thermal driving potential during both the melting and solidification of the PCM. Energy-based thermodynamic analysis further confirms the dominant role of the heat pipe in heat transport, particularly during the discharging phase. In summary, the PFHSFHP setup is a powerful and reliable passive thermal management method that can be utilized for the next generation of miniaturized electronic devices, offering extended thermal buffering, accelerated heat dissipation, and enhanced operational stability.</div></div>","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"352 ","pages":"Article 121118"},"PeriodicalIF":10.9,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146033468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selection of sustainable underground hydrogen storage systems is a critical research topic for addressing environmental issues caused using fossil fuels. However, decision-makers still lack a consensus-based and sustainability-oriented framework that can comparatively evaluate alternative underground hydrogen storage geological formations under economic, environmental, social, and technical uncertainties, which constitutes a critical barrier to large-scale hydrogen deployment. This issue has become more prominent as fossil-based fuel reserves are gradually decreasing worldwide. In contrast, researchers and practitioners lack a consensus on which underground storage method is most suitable for economical, safe, and efficient hydrogen storage. If this problem is not addressed correctly and reasonable solutions are not obtained, continued dependence on fossil fuels may persist. Alternatively, other renewable energy sources with relatively lower efficiency and performance may be adopted. In both cases, significant delays in achieving the global sustainability goal are likely to occur. We propose an integrated fuzzy decision-making framework (F-WENSLO &amp; Dombi-Bonferroni &amp; F-ARTASI) to address this selection problem under uncertainty. The proposed framework integrates fuzzy WENSLO (Weights by ENvelope and SLOpe) for robust sustainability-based criteria weighting, the Dombi–Bonferroni aggregation operator to model interdependencies among criteria explicitly, and the fuzzy ARTASI (Alternative Ranking Technique based on Adaptive Standardized Intervals) method to provide flexible and stable ranking of geological alternatives beyond rigid distance-based approaches. Key advantages of the proposed model include producing reliable and consistent solutions that accurately reflect real-world conditions for selecting sustainable underground hydrogen storage systems. The results revealed that C14 (job creation and employment opportunities) (0.0603) is the most influential criterion in selecting the most suitable storage system.
