At the macroscopic level, the optimized design significantly improves the coal loading efficiency of coal particles by adding circular arc-shaped coal guide plate and triangular coal guide plate. Simulation experiments show that the average mass flow rate of the coal-guided drum is increased by 14.1%, and the mass flow rate under high load conditions is increased by 9.1%; with the increase of the rotational speed, the maximum increase of the loading efficiency is 16.96%. At the microscopic level, the optimized design changed the movement direction of coal particles, which led to a 15.85% increase in axial velocity and optimized the flow structure of coal particles.

The low carbon rationality of the power generation structure in different regions was evaluated and comprehensive evaluation scores were calculated based on an improved C-E-G-T model. The results of the study were as follows. (1) The low-carbon rationality of power generation structure is better in the western region and worse in the central region. In particular, performance was consistently good in Qinghai, Yunnan, Ningxia, and other regions and was poor in Beijing, Shanghai, and other regions. (2) To ensure the reliability of the evaluation results and a high degree of differentiation, the optimal range of values for the α parameter was (0.3, 0.7) in this paper.

Focused on single-fissure sandstone, this study conducts triaxial compression tests with real-time ultrasonic monitoring to investigate the relationship between ultrasonic wave propagation patterns and stress evolution in single-fissure rocks. By utilizing ultrasonic wave velocities to establish macroscopic damage variables for fractured rocks and employing the Weibull probability distribution model to define mesoscopic damage variables, a coupled macro-meso damage constitutive model for fractured rock was developed in conjunction with continuum damage theory. The reliability of the model was validated through analysis of experimental data. Results indicate that under triaxial compression conditions, the ultrasonic wave velocity of fractured sandstone exhibits non-monotonic variations with stress. Damage evolution involves an initial weakening followed by a damage accumulation stage. Wave velocity is negatively correlated with damage extent during the damage growth phase and shows a negative correlation with crack width during stress loading. In addition, the failure mode of rock is basically shear failure and tensile-shear mixed failure. The rock crack initiates at the tip of the prefabricated crack and extends to the top, bottom, or side of the specimen at a certain angle with the prefabricated crack.

Abundant and freely accessible solar energy offers a promising solution to this challenge. Despite the global development of various solar cooking devices, BTSC has not achieved the anticipated level of popularity. This study aims to explore the factors hindering the adoption of BTSC and to discuss how these findings can inform the design of future BTSC models, focusing on four key areas. These include proposing innovative design features to align with the Indian lifestyle, identifying opportunities in nonurban areas, and providing commercialization strategies. The evaluation relies upon the Weight-decision method, results of ethnographic study, potential user analysis using qualitative techniques, and an assessment of commercialization strategies by examining feasibility. The study highlights the need for hybridizing the BTSC by incorporating features such as active tracking, a secondary heating source (battery or grid-operated heating coil), and self-power generation through thermoelectric conversion to increase user acceptance. nonurban users-including those in semi-urban, rural, tribal, nomadic, and trekking communities-demonstrate suitability for efficient solar cooker use. The continued subsidy by the Haryana government has crucially promoted BTSC adoption. Additionally, 30 out of 34 states fall within the high radiation zone, indicating favorable conditions for the adoption of BTSC. However, the assessment also reveals a limitation in the new design related to indoor cooking. These design features should be incorporated into the prototype in the future.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 3","pages":"1037-1061"},"PeriodicalIF":3.5,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602718","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}

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.

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.

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}

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.
