In order to explore the influence of high temperature on sandstone, This study used experimental samples of sandstone from Shaanxi, China. Sandstone samples were subjected to varying temperature gradients (25℃, 100℃, 300℃, 500℃ and 700℃) for Uniaxial Compressive Strength (UCS), Acoustic Emission (AE) monitoring, and Nuclear Magnetic Resonance (NMR) experiments. The resulting mechanical parameters and pore diameter distributions of the sandstone under various temperatures were compared and analyzed. The results showed that: Peak strain and peak stress of sandstone samples both greatly rise and decrease with increasing heating temperature. The degree of elastic modulus and peak stress degradation is also more pronounced at higher temperatures. The brittle-ductile transition occurs at about occurs between 500°C~700°C. At temperatures between 25°C and 500°C, the peak AE energy occurs near the peak strength of the sandstone. The ringing counts of the sandstone specimens reached a maximum after the peak stress when the temperature was 700°C, and the peak AE energy gradually decreased at higher heating temperatures. The T2 spectrum curve and pore size curve of the sandstone increased and gradually shifted to the right with the increase of the treatment temperature, and the area of the T2 spectrum and porosity also gradually increased. There is a negative correlation between porosity and total area of T2 spectrum and peak stress and elastic modulus of sandstone under high temperature. The micropores showed a monotonically decreasing trend with increasing temperature","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"60 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study models available in the literature that represent foams with solid accumulation at the nodes are investigated and used to obtain predictive equations for the permeability (for both the Darcy and Forchheimer flow regimes) and specific surface area for given porosity and average pore diameter values. The majority of the predictive equations proposed for the specific surface area based on these models are novel contributions. Furthermore, a method is proposed for incorporating solid lumps at the nodes into the existing foam (or three-strut) rectangular Representative Unit Cell (RUC) model. The models obtained from the literature along with the node adjusted RUC model are compared to one another and to relevant experimental data from the literature for foams that have accumulation of solid matter present at the nodes.

As media heterogeneity increases, the error of traditional algorithms become uncontrollable due to their significant underestimation of nodal transmissibility. However, the transmissibility calculated in FAM is based on a local analytical solution and its accuracy is not dependent on the strength of heterogeneity. The proposed FAM-9P scheme offers two distinct advantages. Compared to the traditional 9P scheme, it provides much more accurate simulation results, especially for strongly heterogeneous porous media. Additionally, compared to the FAM-5P scheme, it can alleviate grid orientation effect (GOE) under adverse mobility ratios.","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"2 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents the innovative five-sphere model by employing the capillary flow, pore-throat, flowing around models. The flow resistance of the five-sphere model incorporates capillary flow resistance, local resistance caused by the changes of pore-throat, and flowing around resistance of fluids around the filling material, which is summarized to derive a formula for the flow resistance of porous media without empirical parameters. Based on 42 sets of experimental data obtained from literature, this paper compares and validates the proposed model. When ,the five-sphere model is compared with the Carman equation, Ergun and WuJinsui equation; when , the comparison made with the Ergun and WuJinsui equation. Out of the 22 sets of data with deviations in the range of 0-30% of the five-sphere model equation for particles with an average diameter of 0.2 mm up to 56.8 mm; porosity ranging from 0.32 to 0.4174, superficial velocities ranging from 0.000038 m/s to 0.5342 m/s; and Reynolds number ranging from 0.124 to 10730. By further analysis of viscous and inertial resistance, it is found that viscous resistance losses from capillary flow and flowing around occupy the main part; when Rep < 30; inertial resistance losses from diameter change and flowing around occupy the main part when Rep > 150. This further confirms that flowing around occupies an important position in the flow resistance of porous media.","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"2 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a more suitable solution should be selected for practical applications.

Clay nanoparticles are essential for enhancing drilling fluid efficiency. The thermal conductivity, viscosity, and boiling point of drilling fluids increase when clay nanoparticles are incorporated, providing resistance to high temperatures and regulating fluid costs. This article illustrates the convection heat transfer in drilling nanofluid while taking into account the significant presence of clay nanoparticles in the fluid used for drilling. The efficient thermophysical characteristics of clay nanofluid are expressed mathematically using Maxwell-Garnett and Brinkman's formulas. The linear PDEs with physical boundary conditions that control the flow phenomena are predetermined. The similarity technique is employed to transmute these PDEs into ODEs and then an efficient bvp4c solver is utilized to find dual solutions. The Nusselt number and skin friction are calculated and displayed in tabular form as well as graphical form along with the velocity and temperature profiles. Multiple solutions are observed in the case of shrinkable sheets as well as in the case of buoyancy assisting flow. The findings demonstrate that when volume concentration increases, the Nusselt number rises noticeably. In addition, the permeability parameter expands the boundary layer thickness in the lower solution, while the contrary behavior is observed in the upper solution.","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"36 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141942559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study uses numerical simulations over a wide range of Reynolds and Darcy numbers. The porous materials used are steel, aluminum, and copper. To determine the contribution of porous material as well as the spiraling effects of the pipe to increased heat transfer, the simulations were also run for a helical coil without porous material and a porous-filled straight tube. The pitch and radius of the coil were varied, resulting in different coil turns for a given length of the pipe. The rate of exergy destruction in different states was calculated to determine the optimal operating point of the system. The study reveals that porous material significantly improves heat transfer in both straight and helical tubes. The optimal performance is achieved at higher Darcy numbers, with heat transfer being independent or dependent on Re. The highest Nu value is around 450 at Da=0.1 and Re=2000, about 103 times and 17 times the Nu in the straight and helical tubes without porous material, respectively. However, the peak value of PEC is 2 and 17 with respect to porous-filled straight tubes and non-porous helical coils. The main achievement of this study is that it shows that porous media can be applied to amplify heat transfer beside the secondary flow in helical tubes under specific conditions. This enhancement occurs when using porous media with high Da numbers, such as Da ~ 0.1.

Seven samples were considered by mixing dry sand and salt crystals with different salt mass percentages (SMP) from 0% to 100%. The electrical responses are explored by measuring the electrical impedance and the global conductance for different SSM filling a small capacitive cell. The influence of frequency and SMP on the electrical conductance and the complex impedance are investigated. It was found that the conductance shows high dispersion with SMP at the whole frequency range and a high dispersion with frequency at low and high frequencies (≤103Hz and ≥105Hz). Impedance diagrams show a frequency dispersion at high and low frequencies that is modeled by an equivalent circuit constituted of three dipoles in series, each one formed by a pure resistance and a constant phase element in parallel. Findings characteristics are directly related to the rate of salt crystals in the samples.

It was found that the stronger the wettability of the water phase, the higher the crude oil recovery rate, and the lower the residual oil in the form of adsorbed oil film; and the larger the Capillary numbers, the higher the crude oil recovery rate. Crude oil in organic pore space is more difficult to discharge compared with that in inorganic pore space, and the recovery rate of crude oil in organic pore space can be effectively improved by increasing the driving pressure and enhancing the properties of the water phase (fracturing fluid).","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"80 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141612024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
