While typical data of the nonvaporization spray characteristics: spray penetration length, spray cone angle, and spray evolution were collected by varying 40–90 MPa of injection pressure at 15 kg/m³ ambient gas density, data representing combustion characteristics, namely the ignition delay, flame development, and heat release rate (HRR) were illustrated under 90 MPa injection pressure, same ambient gas density, and temperature variation of 900–1000 K. Although the fuel mixture spray development trends followed a similar pattern, GB10 and GB20 had an averagely 6.25%–7.7% faster impingement velocity than that of GB00 except for the lowest considered injection pressure. Additionally, the ignition delay reductions were recognized for both GB10 and GB20, with the duration dropping from 1.09 to 1.06 ms and 0.96 to 0.79 ms, respectively.

In terms of thermal–fluidic, the natural circulation operation without a pump increases the reactor safety and resistance to accidents. The normal operation feasibility of the reactor was evaluated with the multiphysics analysis conducted with the Generalized Nuclear Foam (GeN-Foam) code. It was shown that the reactor can maintain stable power under a fixed heat exchanger outlet temperature condition. To increase the natural circulation, the active core region was designed to have a simple cylindrical shape, which induced a stagnation zone with slow velocity near the side wall. Due to the slow velocity, the stagnation zone has a substantially high temperature, and a flow guide was introduced to mitigate the stagnation effect. The impact of the flow guide was evaluated, including the reactivity feedback and delayed neutron precursor drift effect.

In this study, a novel separator was made by boiling cotton rope with solutions of various salts and their concentrations. It was then employed in a dual-chamber microbial fuel cell (MFC) to treat municipal wastewater collected from 25 Area Wah Cantt, Punjab, Pakistan. Batch scale experiments were carried out to evaluate the effect of various variables, that is, different salts (NaCl, KCl, and MgCl₂) and their concentrations (0.2, 0.5, and 1 M) used in separator, wastewater volume (50, 500, and 1000 mL), and aluminum mesh thickness (0.6, 0.8, and 1 mm) on MFC performance in terms of current generation and wastewater treatment for 7 days. Analysis of collected wastewater showed that among the six studied physicochemical parameters, only two, that is, biological oxygen demand (BOD) and chemical oxygen demand (COD) were above the permissible limits of National Environmental Quality Standards (NEQS). Results after MFC experiments showed that separator containing 0.5 M NaCl produced a significantly (<i>p</i> &lt; 0.05) high current of 68.16 µA as compared to the other studied salts and their concentrations, whereas COD and BOD were reduced up to 124.15 and 62.12 mg L⁻¹, respectively.

The primary purpose is to overcome conventional DPC (C-DPC) limitations in doubly fed induction generator wind turbines (WT-DFIG), focusing on power quality improvement and enhanced system efficiency. The techniques aim to reduce power ripples and improve the quality of alternating current (AC) grid energy by improving current signal quality in all WTs’ operation modes with WT-DFIG and all compensation power modes. The suggested techniques are thoroughly examined using the MATLAB/Simulink environment under various wind scenarios, demonstrating a reduction in active power ripples by over 70%, a reduction in reactive power ripples of around 77% on average, a decrease in generated current total harmonic distortions (THDs) by over 70% compared to C-DPC. The performances of FH-DPC and NH-DPC are contrasted with C-DPC and other previously suggested methods, and it is concluded that the proposed control approaches perform more effectively than them regarding ripples in local reactive compensation and generated active powers as well as THD currents, with FH-DPC slightly outperforming NH-DPC.

However, when the percentage of RESs in the energy mix rises, there is a negative correlation between forecasting accuracy and process error, which could impact not only the grid but also the whole RES’s economic sustainability. In order to tackle this problem, this paper examines the economic implications of employing the Analog Ensemble (AnEn) forecasting model within Korea’s solar energy sector. The levelized cost of energy (LCOE) model and the revenue prediction model are applied to assess the efficacy of the AnEn. The proposed revenue scheme scheme was initiated on a 1 MW photovoltaic (PV) ground-type power plant deployed in the mainland of South Korea. Various methods have been examined to assess the financial benefit of utilizing the AnEn, such as forecast verification and LCOE and revenue forecast scheme. Key findings reveal that the AnEn model consistently outperforms traditional models in terms of accuracy, particularly during critical solar peak months. This improved accuracy translates into more reliable predictions of solar irradiance, essential for minimizing overestimations and supporting realistic financial planning. Furthermore, the paper explores the economic incentives implemented by the Korean government to encourage precision in energy forecasting, including a structured incentive scheme tied to forecast accuracy.</p>\u0000 </div>","PeriodicalId":14051,"journal":{"name":"International Journal of Energy Research","volume":"2025 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/er/5529459","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143119891","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}

Many experimental studies of continuous operation cycles have been carried out to gain an understanding of fuel cell durability, ignoring the shutdown and rest process. This paper performed durability tests over 1000 h in total, including the shutdown and rest processes, to investigate the impact of voltage recovery on cell degradation in real applications. Each durability test was operated only 8–10 h per day, and then the stack entered a shutdown and rest process. The results show that the voltage recovery after the shutdown and rest processes makes the fuel cells maintain the performance in the long term. The performance can be higher than the previous stage, which differs from the constant performance degradation observed in continuous tests. This paper specifically investigates the influence of operating conditions on durability, the characteristics of voltage degradation, and the underlying reasons for those phenomena during dynamic cycles that include shutdown and rest processes. The decrease in voltage uniformity is analyzed. The results indicate that imprecise control of the operating conditions could lead to a reduction in the fuel cell durability. During the processes of voltage degradation and recovery, marked improvements in performance are observed. Following the initial rapid decline in performance, the fuel cell degradation exhibited a strong correlation with the variations in voltage uniformity. Notably, the excessive degradation observed in a certain cell was the primary factor contributing to the reduction in voltage uniformity rather than the overall cell’s nonuniform voltage. The shutdown and rest processes are crucial components of the dynamic cycles, and the mechanism of voltage recovery after the shutdown and rest processes should be focused on to improve the fuel cell life.</p>\u0000 </div>","PeriodicalId":14051,"journal":{"name":"International Journal of Energy Research","volume":"2025 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/er/3246950","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118623","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}
