This study used a hollow PEEK conductor to simulate core pores. With excellent thermal stability, mechanical strength, and electrical insulation, its homogeneous, nonporous nature eliminates interference from rock properties, providing an ideal medium for studying pure fluid changes. The resistivity at different temperatures and pressures, and that of different fluids during the displacement process was experimentally measured. The results show that mineralization is the main factor affecting the resistivity, and the resistivity of formation water is reduced by 98.83–99.41% compared with that of deionized water under the same conditions. With the increase of temperature, the ion hydration effect weakens and increases the ion mobility rate, and the resistivity of various fluids decreases by 55.13–66.87%. The effect of pressure on resistivity is relatively weak, and the resistivity is reduced by approximately 2.29–11.08% by reducing the distance between ions and increasing the collision frequency between ions. However, in CO₂-containing systems, increased pressure promotes CO₂ dissolution and ionization of more ions, which results in a larger decrease of 17.72–9.31%. It is particularly noteworthy that CO₂ dissolved in pure water reduces the resistivity by 91.50–94.50%, but when dissolved in formation water, the resistivity increases by 276.63–430.94%. Based on the ideal pore characteristics of the PEEK model, we fix the parameters (a, b, m, n) in the Archie formula to 1, and derive a simplified saturation model: Sw = Rw/(φRt). This achieves the quantitative representation of resistivity monitoring data into saturation distribution, improves the accuracy of calculating CO₂ saturation using resistivity data, and has important guiding significance for interpreting field monitoring data and evaluating CO₂ sequestration. Future research aims to translate these findings into practice using real rock cores.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"14 2","pages":"752-763"},"PeriodicalIF":3.4,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://scijournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70379","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147268965","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}

Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. The numerical solutions were obtained using the steady-state single-phase SST <i>k-ω</i> turbulence model. The results indicate that the region within 2 mm of the wall contributes the majority of the FED production in both pump and turbine conditions. This portion of the FED is influenced by the viscosity-dominated flow-wall interaction. In pump condition, the highest FED production occurs in the return channel, with the backward vane and forward vane regions contributing 38.3% and 14.4%, respectively. In turbine condition, the highest FED production occurs in the runners, with the first and second-stage runners contributing 43.7% and 21.4%, respectively. To enhance efficiency in both modes, reducing the surface roughness of the flow channels is recommended.

None of the existing methods of estimating the GCV of coal go into detail about deployment within real-time monitoring systems at coal-fired power plants (CFPP). This study applied a novel approach of using real-time plant data to estimate the GCV of coal by employing computational fluid dynamics (CFD) and mass and energy balance (MEB) modelling to simulate a full-scale coal fired boiler since currently, the plant does not have enough data to establish a correlation between the GCV of coal and real-time plant data.

This study evaluates a novel financing mechanism for renewable electricity in Iran that leverages profits from the petrochemical industry and carbon tax revenues to support a feed-in tariff (FIT) model. By reallocating natural gas from inefficient fossil-fuel power generation to high-value petrochemical production, the approach enhances economic value, reduces CO₂ emissions, and promotes renewable energy deployment. Iran plans to expand its petrochemical production from 91.5 million tons in 2022 to 183 million tons by 2033, which will drive a 166% increase in demand for fuel and feedstock. Given these resource constraints, integrating renewable electricity into the grid is critical for sustaining industrial growth. System dynamics modeling indicates that carbon tax revenues could reach between $3.8 billion and $37.7 billion by 2033. Meanwhile, the profitability of the petrochemical sector shows wide variability depending on product prices, with a 326% spread between optimistic and pessimistic scenarios. The resulting FIT ranges from 6.24 to 20.29 cents per kilowatt-hour, with higher carbon taxes being particularly beneficial under low-price scenarios.

Different techniques and models have been proposed for performance prediction of axial compressors. Because of its lower computational cost and high speed the meanline algorithm has been widely applied in preliminary design and analysis of axial compressors; however, there are some inaccuracies at design and off-design conditions since the method relies on empirical correlations, which may be weak when applied to unconventional airfoil types. Applying some modifications to the meanline algorithm could improve its performance for a wider operating range with higher accuracy. This study aims to propose a modification for accuracy enhancement of meanline techniques to obtain characteristics of axial flow compressors at design and different off-design conditions. For this purpose, three scenarios are considered to modify the models. In the 1st scenario, coefficients are used for the deviation models while the pressure loss was not changed, in the 2nd scenario coefficients are applied for the pressure loss models and the deviation model is used as the base model and in the 3rd scenario, coefficients are used for both models. The coefficients are optimized by use of multi-objective genetic algorithm. It was found that use of the 3rd scenario leads to the best accuracy. In this scenario, the average absolute error in the estimated isentropic efficiency is reduced from 2.41% to 0.75% at 80% design rotational speed while the improvement in estimated mass flow rate at this speed is relatively minor.
