The heat transfer mechanism, particularly multilayer interaction, is numerically studied by investigating the intersection angles within the multilayer interacted characteristic melting region. Based on the mechanism, partially/fully filled foams with constant material are investigated to attain the optimal filling strategy. Furthermore, the economic analysis is employed to evaluate the cost performance under different porosities. Results indicate the multitube unit is affected by the natural convection development and the influenced area of multilayer interaction. Cases with intersection angles of 90°/240° reduce melting time notably by expanding interaction area without impairing natural convection. Maintaining constant material usage, the foam is expanded across the melting region. Compared to the partially filled, the melting time is reduced by 63.16 % because the influenced area of multilayer interaction covers the whole melting region. For the comprehensive evaluation, the fully filled foam with 0.92 porosity demonstrates superior comprehensive performance.

This study provides a comprehensive analysis of the phase behavior and thermodynamic responses of medium-high maturity continental (HMC), medium-low maturity continental (LMC), and marine (Bakken) shale oils under CO₂ injection. Experimental data and phase behavior modeling reveal distinct trends in saturation pressure, molecular weight, volume expansion, viscosity, and the critical role of light-to-heavy component ratios. Key findings show that, generally, CO₂ injection initially raises and then lowers saturation pressure, while the high methane content in HMC A induces a continuous decrease in saturation pressure, shifting from an oil-gas coexistence state to a pure oil phase. Increased CO₂ results in significant reductions in viscosity and molecular weight, especially in LMC, and promotes volume expansion in HMC and Bakken oils. Light-to-heavy ratios significantly influence phase behavior, with higher methane content enhancing CO₂ solubility. Furthermore, simulations indicate that achieving miscibility requires high pressures and CO₂ concentrations, with HMC A exhibiting backward-contact miscibility in contrast to the forward-contact miscibility seen in other oils.

Axial flow pumps, as an energy conversion device, play an important role in pumped storage and water source transportation. However, axial flow pumps experience severe energy loss under low flowrates, affecting the energy performance and stability of the hydraulic system. This paper proposed an inclined groove flow control method to improve the performance at the saddle zone. The performance was investigated experimentally and numerically with and without grooves. The result shows that inclined grooves significantly enhance the energy characteristics at the saddle zone, with a 56.5 % increase in head at 0.4<em>Q</em>_<em>des</em> and a 40.17 % increase at 0.5<em>Q</em>_<em>des</em>. The local low-pressure zone upstream and downstream of the inclined groove creates a reverse flow inside the groove, mixing with the mainstream in the inlet pipe and weakening the circumferential angular momentum. The improved inflow condition mitigates flow separation within the pump and suppresses the propagation of tip blockage vortex. Entropy production analysis reveals that inclined grooves effectively suppress energy losses in the inlet pipe. Moreover, a dimensionless number <em>NOG</em> is proposed for the design of the inclined grooves. It is found that the ideal <em>NOG</em> range is between 0.014 and 0.022, which optimizes energy performance in the saddle zone while minimizing negative effects under the design condition.</div></div>","PeriodicalId":11647,"journal":{"name":"Energy","volume":"328 ","pages":"Article 136527"},"PeriodicalIF":9.0,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947880","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 objective is to assess efficiency improvements, energy savings, and sustainability compared to a dual-temperature air-source heat pump (DTHP) and standard heat pump systems, particularly in cold climate applications. A validated thermodynamic model was developed to analyse two proposed DTEHP configurations using four zeotropic mixtures: R1234ze(E)/R600, R1234yf/R1233zd(E), R600/R290, and R600a/R290. The zeotropic mixtures exhibit ultra-low-global warming potential and ozone depletion potential, making them environmentally sustainable alternatives to traditional refrigerants. The performance of these systems was evaluated in terms of effects of high-temperature condenser inlet saturated temperature, low-temperature condenser outlet temperature, ambient air temperature, load ratio and zeotropic mixture mass fraction on system heating coefficient of performance (COP&lt;sub&gt;h&lt;/sub&gt;), volumetric heating capacity, exergy efficiency, and entrainment ratio. The results demonstrated that zeotropic mixture composition significantly influenced system efficiency. The analysis revealed that the DTEHP2 system consistently outperformed the other configurations across all zeotropic refrigerant mixtures, delivering the highest values for COP&lt;sub&gt;h&lt;/sub&gt;, volumetric heating capacity, and exergy efficiency. The DTEHP1 system also demonstrated significant performance improvements over the DTHP system, validating the efficacy of ejector-based enhancements in improving system performance. More specifically, the DTEHP2 system achieved the highest COP&lt;sub&gt;h&lt;/sub&gt; ranging from 4.912 to 5.334; demonstrated the highest volumetric heating capacity among all systems, with values peaking at 2695.68 kJ/m&lt;sup&gt;3&lt;/sup&gt; for R600a/R290, and delivered superior exergy efficiency, with a maximum of 56.37 % using R1234ze(E)/R600. The DTEHP1 consistently displayed higher performance than DTHP, with COP&lt;sub&gt;h&lt;/sub&gt; values ranging from 3.665 to 3.957; the volumetric heating capacity and exergy efficiency followed similar trends, reinforcing the impact of the ejector in improving system efficiency. In DTEHP configurations, R1234ze(E)/R600 and R600a/R290 offered the best overall performance. The integration of an ejector in the system led to efficiency improvements ranging from 10 % to 120 % over a standard DTHP system. The DTEHP2 system, in particular, achieved COP&lt;sub&gt;h&lt;/sub&gt; enhancements of up to 86 %, confirming the effectiveness of ejector-assisted cycles. The results suggest that R1234ze(E)/R600 and R600/R290 offer a balanced trade-off between performance and environmental impact, making them viable alternatives to conventional high-GWP refrigerants.

The multi-body and multi-coupling interaction among WECs, mooring chains, cage nets, floating collars and cage sinkers are investigated. The results reveal that, across all simulated wave periods, rear-positioned WECs exhibit higher wave energy conversion efficiency than front-facing units, primarily due to the reduced constraints imposed by the mooring chains. Compared with taut mooring, the catenary mooring configuration increases wave energy conversion by 50 % in long-period waves and reduces facing-wave mooring tension by 13 %. Under identical physical parameters, square and in-line cage configurations demonstrate superior wave energy conversion performance, whereas front–back arrays induce greater mooring tension. PTO units partially offset the mooring tension, so the optimal PTO damping for WECs in the hybrid system is higher than for isolated WECs and increases along with wave propagation.

However, existing HWS planning models often oversimplify VRE output characteristics, neglecting spatial heterogeneity. Furthermore, these models mostly rely on deterministic inputs, overlooking uncertainties. To address these limitations, we introduce an integrated optimization framework that optimizes capacity mix at a site-specific spatial resolution, incorporating uncertainties from technological, climate, policy, and market changes. Applied to China's Yalong River HWS base, the framework results in a 7 % increase in economic benefits and an 18 % reduction in VRE capacity compared to models that ignore resource heterogeneity. Under varying conditions, cost-effective generation from the HWS system achieves over 80 TWh per year, representing 68 % of its total potential, with an optimal transmission line capacity of 12,375 MW.

To address this, we propose SDM-VMD-IENN, a novel framework integrating Similar Data Matching (SDM), Variational Mode Decomposition (VMD), and an Imbalanced Evolved Neural Network (IENN). This model uniquely combines data enhancement and evolutionary optimization to overcome the limitations of existing methods, including negative transfer effects in transfer learning models, data redundancy, and local convergence. Specifically, SDM mitigates negative transfer by filtering highly similar source domain data and constructing Gram matrix-based feature representations, enabling precise selection of high-similarity samples from the source domain. VMD decomposes non-stationary wind power sequences into stable subcomponents, reducing the nonlinear complexity of temporal features. IENN balances sample distribution discrepancies through evolutionary multi-loss optimization and adaptive weighting strategies based on distribution similarity, achieving global convergence. Experiments on real-world wind farms demonstrate that the proposed model exhibits higher prediction accuracy and enhanced robustness compared to classical models and other evolutionary frameworks, particularly under data scarcity scenarios. In our single-step and multi-step prediction tasks, SDM-VMD-IENN consistently outperforms traditional deep learning and evolutionary models. It effectively lowers RMSE and MAE.
