In the related research, there are many reports on the stability analysis of the laminar split structure under static loads and few reports on the stability analysis under dynamic loads. This paper addresses the stability of surrounding rock in deep roadways, focusing on the key factor of disturbed load. First, the paper theoretically establishes the control equation for analyzing the dynamic stability of the laminar split structure in the coal wall of roadway, deriving the minimum critical load for instability of the laminar split structure under two constraint conditions: simply supported at both ends and fixed at both ends. Second, using discrete element software, the paper analyzes the influence of disturbing load on the stability and energy accumulation characteristics of the surrounding rock of the roadway. It examines the variation patterns of stress in the surrounding rock, deformation of both sides and roof-floor, distribution of plastic zones, and energy accumulation characteristics with respect to time t and the intensity of disturbing load pmax. Finally, the paper analyzes the stability of surrounding rock in a mine involved in a rock burst accident. The research results provide a basis and reference for analyzing the risk of rock burst under similar conditions.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 3","pages":"1337-1360"},"PeriodicalIF":3.5,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2074","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It discusses the progress in the study of heat exchangers under different sloshing conditions, including theoretical models and comparisons of various swaying conditions, and comprehensively reviews the key factors influencing the enhancement or deterioration of heat transfer in heat exchangers. The research indicates that increasing the swing amplitude of spiral tube heat exchangers, reducing the swaying period, and other methods can enhance heat transfer; conversely, increasing the rolling amplitude of coil heat exchangers, extending the pitch period, and similar actions can weaken heat transfer. The mass flow rate of the working medium, steam quality, and the parameters of the sloshing motion affect the uniformity of medium distribution. When the sloshing factor is introduced, the correlation of heat transfer is highly related to the range of dimensionless numbers (such as Re and Pr) and the physical dimensions of the heat exchanger. Additionally, the article discusses techniques to mitigate the negative effects of swaying and improve heat transfer performance through improved distribution methods. Overall, the article provides significant insights into understanding the thermo-mass transfer performance of heat exchangers in marine environments, offering valuable references for engineers and researchers in related fields.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 4","pages":"2164-2178"},"PeriodicalIF":3.5,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, different hydrophobic functional groups were used to graft on the surface of SiO2 nanoparticles for wettability alteration applications. The synthesized nanoparticles were identified and optimized using contact angle measurement and Fourier-transform infrared spectroscopy (FTIR). At last, core flowing experiments combined with NMR tests were conducted to study the fluid flow properties of low porosity and permeability reservoirs. Based on the results obtained in this study, the nanoparticles modified by KH570 have the best hydrophobic effect, the optimal reaction conditions including pH = 6, reaction temperature of 84°C, and modifier dosage of 25%.

Environmental factors such as icing, insects, dust, and pollution contribute to blade roughness, increasing aerodynamic drag and reducing power output. In this study, a Monte Carlo simulation is employed to analyze the effects of surface roughness on key variables, including the power coefficient, rotor torque, generator speed, and blade pitch angle in two distinct operating regions: partial load and full load. The results indicate that in the partial load region, increased roughness leads to a reduction in the power coefficient, generator speed, and rotor torque, ultimately lowering power output. However, in the full load region, the control system compensates for roughness effects by adjusting the blade pitch angle, maintaining a nearly constant power output. This study provides a probabilistic analysis of roughness effects, aiding engineers in developing optimized strategies for wind turbine design and maintenance to minimize energy losses and enhance efficiency.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 4","pages":"2022-2030"},"PeriodicalIF":3.5,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, a three-dimensional analysis model of a high-voltage resistance MSEH is developed using ANSYS Fluent. This study focuses on the overheating issue in the molten salt, investigating the fluid flow and temperature distribution within the electric heater. A multi-zone heating method is proposed, and the heating proportions of different zones are examined in detail. Based on this, the influence of structural parameters is analyzed. The results demonstrate that the multi-zone heating method eliminates the overheating phenomenon in the MSEH and improves temperature uniformity. The maximum temperature of the MSEH decreases from 622.6°C to a maximum of 583.4°C with the multi-zone heating method. The optimal heating proportion of 80-20/2.0 results in a maximum temperature that is only 14.9°C higher than the outlet temperature. The analysis of structural parameters offers valuable guidance for MSEH design. This study successfully suppresses local overheating in the MSEH, efficiently evaluates heating capacity, and ensures system safety.

Hence, this study proposes a virtual cluster partitioning model for active distribution networks using a quantum particle swarm optimization (QPSO) algorithm and sector search, aiming to achieve autonomy within clusters and coordination between clusters. First, the article proposes a sector search model that transforms the topological connections of the distribution network into mathematical expressions. This model simplifies the search for node locations and improves the algorithm's convergence speed. Building upon the traditional particle swarm optimization (PSO) algorithm, this study introduces the wave function and Schrödinger equation to enhance algorithm performance. By treating the vectors obtained from sector searches as particles, the proposed QPSO algorithm significantly improves both the search efficiency and global convergence in solving the virtual cluster partitioning model. Finally, case studies conducted on the modified PG&E 69-node system demonstrated the proposed method's significant advantages. The method improved computational efficiency, with a cluster power supply rate over 0.6 and modularity above 0.7, ensuring balanced partitioning. The scalability and effectiveness of the proposed method were validated on an 85-node system, achieving balanced cluster partitioning with high operational efficiency and adaptability.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 4","pages":"1883-1895"},"PeriodicalIF":3.5,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lack of appropriate alternative coarse and fine aggregates essential in concrete production is one of the critical issues faced by the construction industry. This review evaluates its environmental benefits, chemical and physical attributes, and influence on GPC's microstructure. Previous studies have shown that incorporating POC in GPC significantly reduces density from 2345 to 1821 kg/m3 while maintaining competitive compressive strength, thus proving its applicability in various structural and nonstructural contexts. Moreover, GPC with POC demonstrates enhanced resistance to aggressive environmental conditions such as water absorption and resistance against acid and sulfate environments. Geopolymer mortar (GPM) exposed to sulfate attack recorded the lowest decrease in strength than GPM containing POC fine aggregates by about 20%. The use of 100% POC aggregates in GPC mix has a 3.2% water absorption, which is lower than the limit for high-performance concrete. The results advocate for the development of POC-aggregate GPC as an environmentally friendly construction material, contributing to the sustainable advancement of the building industry.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 3","pages":"958-979"},"PeriodicalIF":3.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.1977","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the presented topology, a three-winding coupled-inductor (TWCI) and a switch-capacitor network are employed in a classic quadratic boost converter to produce a high voltage gain while ensuring continuous input current and common ground between the input source and output load sides. This circuit has a semi-trans-inverse feature; therefore, higher voltage gain can be obtained under a very low number of turn ratios of the TWCI. Moreover, the current sharing between the TWCI and input inductor of this topology minimizes the power dissipation of the active switches and the magnetic components. In this circuit, two passive clamp circuits are used to limit the voltage stresses of the active switches, which are operated in simultaneous switching patterns. Detailed steady-state analysis, power loss estimations, comparison studies, and design considerations are provided.
