This is an important source for converting energy from one form to another while utilizing electromagnetic induction. This phenomenon is efficient when the induced magnetic field is introduced in the materials' wavy motion affected by mass and heat gradients. The complex, wavy dynamics of the materials become more useful if the heat transfer is effectively enhanced via the external thermal radiation. These aspects are explicitly studied in this study. The mathematical equations formulated in the presence of these aforementioned effects are based on the low Reynolds number. Every physical trend is validated through a test of the relevant parameter while plotting its graphical view. The results offer valuable insights for the design and control of advanced fluid systems where these effects play a crucial role in system performance. Flow, thermal, and mass transfer analyses are comprehensively addressed. An explicit and significant influence of the induced magnetic factor on the flow pattern is noticed. The material factor reduces the surface drag force, and the Dufour and Soret numbers both reduce the heat and mass flows, respectively. The reciprocal magnetic Prandtl number uplifted the wavy flow speed of the material, and an opposite conduct is detected through the magnetic factor. The radiation effect enhanced the material temperature, and a reduction in the concentration was noticed while plotting the behavior of the chemical reaction factor.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 10","pages":"4917-4932"},"PeriodicalIF":3.4,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://scijournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70217","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272960","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 proposes a fully independent parallel compensator, implemented as a voltage-controlled current source, to effectively suppress PV current ripple. A hybrid control strategy is introduced, combining a proportional-resonant (PR) controller for steady-state error elimination with a Dead-Beat (DB) controller to ensure fast dynamic response.

Taking the Chang 6–Chang 9 layers of the Yanchang Formation in the Wuqi area of the Ordos Basin as a case study, we examined the pore types, pore structures, and associated parameters of the tight sandstone, and explored the influence of sedimentary microfacies on these characteristics. The results show that the pores in the tight sandstone are mainly dissolution and intergranular, followed by intercrystalline pores and microcracks. The tight sandstone formed by underwater distributary channels exhibits relatively more dissolution and intergranular pores, with the leading edge sheet sand being next in abundance. In contrast, the sedimentary microfacies of underwater natural embankments contain fewer intergranular and dissolution pores, while intercrystalline pores and microcracks are observable. The pore diameter distribution range of tight sandstone formed by underwater distributary channels is broad, ranging from nanometers to tens of micrometers. In contrast, the pore diameter distribution of tight sandstone formed by leading edge sheet sand is relatively narrow, ranging from nanometers to a few micrometers. The pores of tight sandstones formed by underwater natural embankments are mainly found on the nanometer scale. The fractal analysis indicates that the pores of underwater distributary channels are more regular and smoother in surface texture. Due to the differences in original sedimentary compositions, sorting properties, and roundness of tight sandstones formed by different sedimentary microfacies, the primary pores also exhibit significant differences.

The paper proposes a technique based on Principal Component Analysis for coherency identification to select signals for observability, and a novel method of dimension reduction by Sequential Orthogonalisation to select signals for controllability. Additionally, the paper considers a simple damping controller circuit that takes inputs from wide-area signals to control inter-area oscillatory modes using conventional power system controllers. The proposed scheme is tested on the modified 39-bus New England Test System under a variety of operating conditions, and the results show a significant improvement in the damping performance of the system.

Different from one single fracture, the slurry almost simultaneously flows to multiple fractures in staged multicluster fracturing, resulting in a more intricate distribution of proppants, which directly affects the hydrocarbons production. To study the distribution of SC-CO₂-carrying proppants in multicluster fractures, a physical model consisting of a horizontal wellbore, three perforation segments, and three clusters of fractures was constructed. On the basis of experimental testing of SC-CO₂ permeability in the shale matrix, a two-phase mixture flow model coupling slurry flowing in fractures and SC-CO₂ filtrating into the shale matrix was proposed to predict the proppants distribution within multiple clusters of fractures. To facilitate the smooth transition of two-phase flow from the wellbore to fractures, the equivalence method of flow velocity and pressure drop was employed to convert perforation segments into conical regions. Finally, the application of principal component analysis allowed for the identification of the degree to which different parameters influence the proppant distribution. The simulation demonstrates that fractures located closer to the inlet of the sand-carrying fluid within a given fracturing section exhibit a larger sand-filling area and higher proppant concentration. Furthermore, it is observed that the proportion of each cluster of fractures with the proppant concentration below 3% constitutes more than 50% of the whole fracture area. Reducing the slurry viscosity, increasing the displacement and sand proportion of slurry, and enhancing the perforation density can yield two benefits: an amplified proportion of sand-filling areas within fractures, and augmented areas with high proppant concentration. Among the four parameters studied, perforation density and slurry sand ratio are primary factors that affect the proportion of total sand-filling area and high proppant concentration filling area in the fracture, respectively.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 10","pages":"4853-4867"},"PeriodicalIF":3.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://scijournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70213","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272209","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}

However, research on its underlying mechanism and key parameters remains limited, particularly regarding the failure mechanisms of the drilled holes. This study presents, for the first time, a three-dimensional analysis of the fracture mechanism of roofs subjected to dense drilling and establishes a mechanical model to explain the combined tensile-shear failure along the drilled holes. Key factors influencing the cutting effect—namely drilling height, angle, diameter, and spacing—are identified through numerical simulations, which also clarify the impact mechanisms of these variables on roof fracture. The results indicate that excavation of the working face alters the original stress state of the roof. Specifically, the stress on both sides of the borehole shifts from compressive before excavation to tensile after excavation, leading to tensile-shear composite failure of the surrounding rock and causing roof collapse along the fracture lines formed by the dense boreholes. Drilling height, angle, and spacing are found to negatively affect roof fracturing, whereas increased hole diameter and B/D (borehole spacing-to-diameter) ratio exert a positive influence. Finally, a rational method for calculating the key parameters of RCDDH is proposed and successfully implemented at the Longtan Mine in Sichuan, China.
