Furthermore, the diffusion behavior of methane within organic matter is crucial for enhancing shale gas production. Understanding the diffusion behavior of methane in nanopores is essential for unraveling the mechanisms of methane transport. In this paper, a lattice Boltzmann model was constructed to investigate the diffusion effects of methane in sinusoidal channels. The study examined the influence of the number, amplitude, and spacing of the protrusions in sinusoidal channels on methane diffusion. It was observed that methane is significantly influenced by large-amplitude protrusions, leading to an increase in diffusion velocity at the protrusion region. Before passing through a protrusion, methane concentration rises, while it decreases after passing through it. When multiple protrusions appear consecutively, methane struggles to form effective continuous diffusion pathways, resulting in significant variations in diffusion velocity. However, when the protrusions are misaligned, methane diffusion is affected only by the protrusions on one side, enabling the formation of continuous channels and maintaining high diffusion velocities. The LBM results provided in this paper will contribute to understanding the diffusion mechanisms of methane in irregular nano-channels.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 10","pages":"4973-4990"},"PeriodicalIF":3.4,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://scijournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70222","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145271933","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 aim of this article is to investigate the effect of the optimal corona ring dimensions on the electric field and the potential distribution when the insulators are dried and wetted with salty pollutants dissolved in water droplets. The electric field of the outdoor polymeric insulator is inspected by the use of FEM software and the COMSOL multiphysics program. The 220 kV (RMS line voltage) actual models of the polymeric insulators are used in the study by the use of the 2D model. From the intensive study, it is concluded that the maximum value of the electric field in the absence of the corona ring reaches 13.89 kV/cm and decreases to 1.63 kV/cm (i.e., about 88% of its initial maximum value), in the case of using the optimal dimensions and location of the corona ring. In addition, the proposed corona ring dimensions to be used in high voltage polymer insulators have proven to be suitable in the case of the polluted insulator by salty pollutants dissolved in water droplets as well as the field reached very close to the E-field values that are recommended by the EPRI and IEEE specifications. In addition, this study helps in the development of corona ring dimensions to maximize the corona ring impacts on the polymeric insulators with respecting the industrial specifications.

This model has enabled delineation of vertical and planar distribution patterns of coal macrolithotypes within the #5 and #8 coal seams of the Daji block, as well as to forecast the distribution of favorable reservoir conditions. Our findings indicate that semibright coal is predominant in the deep layers of the Daji block, with semidull, bright, and dull coals occurring less frequently. There is a strong correlation between the content of vitrain and clarain and the logging parameters of AC, DEN, GR, and M2RX. The accuracy of the logging response model for coal macrolithotypes is as high as 80%. Vertically, in both the #5 and #8 coal seams, the Yichuan–Hedong area is characterized predominantly by bright and semibright coals, while semidull coal is the dominant type in Yanchuan. Specifically, within the #8 coal seam, the Yichuan–Hedong area is largely composed of semibright coal, whereas the eastern part of Yanchuan is dominated by semidull coal. In terms of planar distribution, the #5 and #8 coal seams exhibit a development of semibright and bright coals in the Yichuan–Hedong and northern Yanchuan regions. Notably, the combined content of bright and semibright coal in the #8 coal seam exceeds that of the #5 coal seam. Based on the proportion of bright coal plus semibright coal as an index, the reservoirs have been categorized into three types. The middle and upper sections of the #8 coal are identified as the primary reservoirs, while the areas adjacent to the dirt band and the lower sections are considered less favorable for reservoir development.

This study investigates the potential of Fresnel lenses to enhance the thermal efficiency of solar collectors by analyzing the effects of water flow channel structure and flow rate on heat gain. A physical module with varying thicknesses and widths was established to examine the influence of structural parameters on outlet temperature and heat gain under different flow rate conditions. The results indicate that at low flow rates, increasing the collector thickness significantly improves heat gain. However, at higher flow rates, the impact of collector thickness diminishes as convective heat transfer dominates. While increasing the flow rate enhances heat gain, marginal effects are observed beyond a certain flow rate, where further increases provide limited improvements. At flow velocities below 0.32 m/s, heat gain decreases with increasing channel width, a trend more evident at lower velocities. Conversely, at flow rates exceeding 0.32 m/s, heat gain initially rises with increasing channel width, then decreases and stabilizes. At the same flow rate, heat gain generally increases with wider flow paths, although at a flow velocity of 0.02 m/s, channel widths exceeding 34.8 mm show a declining trend. Notably, at a flow velocity of 0.92 m/s, increasing the channel width from 34.8 to 44.28 mm results in a substantial enhancement in the heat gain.
