The HNF is prepared with the addition of AA7072 and AA7075 (aluminum alloys) nanoparticles (NPs) in water. Aluminum alloys are frequently used in aircraft parts like fuselages and wing flaps due to its light weight and durability. Additionally, making of M16 rifles for the American military is one intriguing application of the aluminum alloys. The fluid flow has been estimated with the significances of thermal radiation, DF effect, viscous dissipation, thermal slip condition and exponential heat source/sink. The modeled equations are simplified to ordinary system of differential equations (ODEs) by substituting similarity variables. The obtained set of equations is solved via using PCM (parametric continuation method). It has been noticed that the HNF both radial and axial velocity diminish with the upshot of porosity parameter and Darcy Forchheimer term. The velocity and temperature fields reduce with the rising numbers of aluminum alloys (AA7072 and AA7075).","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"39 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140075634","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}

With the aid of the Galerkin 1st approximation technique, the numerical examination is carried out. The Darcy-Brinkman porous media and particles suspension are taken into consideration throughout the conduct of this study. The non-Newtonian Casson nanofluid, Darcy-Brinkman porous medium, particle suspension and rotation parameter, their impact on thermal convection have been analysed and presented graphically for free-free, rigid-rigid and rigid-free boundaries. It is found that for all boundary conditions: the Casson nanofluid and suspended particle parameters have destabilising impact on the stationary convection whereas the parameter which occurred due to presence of rotation i.e. Taylor number and Brinkman porous medium parameters, they both delayed the stationary convection. In addition, we have discovered that for realistic rigid-rigid boundary condition, the system is determined to be more stable than for the other two boundary conditions. Also, on the basis of several approximations on the Taylor number and other parameters, the critical wave number and value for stationary convection are determined.","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"57 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140196674","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 fluid layer flows over a curved stretching surface. The movement is taken across a permeable medium and under the influence of thermal diffusion, diffusion thermo, an unchanged vertical magnetic field (MF), Joule heating, thermal radiation, and chemical reactions. The mathematical construction comprises momentum, energy, nanoparticles volume fraction, and microorganism concentration equations along with linear slip velocity and suitable boundary conditions (BCs). The motivation of the problem concerns recent progress in curved electronics and microchip technology which made a growing development to the remarkable disadvantages of traditional planar electronics, from which the importance of the current work stems. Furthermore, the implication of this work emerges from the participation of microorganisms in the flow over a curved surface and the equation that this flow shares with the temperature, velocity, and nanoparticle system of equations. This prototype has a considerable applicable role in some manufacturing and engineering mechanisms like conduits, sports balls, combustion, inflated broadcast, and flow-structure contact between hydrodynamics and aerodynamics. The configuration of nonlinear partial differential equations (PDEs) is converted into ordinary differential equations (ODEs) by consuming suitable symmetrical transformations. The resulting equations are numerically analyzed via the fourth-order Runge-Kutta (RK-4) in concurrence with the shooting technique.

To fully understand the potential environmental impacts of HAZMAT accidents, estimating the potential spread for various HAZMATs is needed for a complete risk assessment. We conducted diffusion tests on porous filter paper for four HAZMAT compounds —methanol, ethanol, hydrochloric acid, and sodium hydroxide—on unmodified α-cellulose filter paper using conservative (nonreacting) dye tracers. We determined spread area, time of diffusion, porosity, and retention factors among other properties. The analytes showed that the chemical dispersion properties are distinctly different. For example, the range of retention factors of ionic solutions, although similar for methanol and ethanol, was significantly different for hydrochloric acid and sodium hydroxide. Temperature also has an impact on dispersion properties. The diffusion area for sodium hydroxide increased in temperature while its viscosity decreased. All other analytes diffusion increased with increasing temperature. An analytical solution using an amplitude diffusing mass model was used to estimate the diffusion coefficients of each analyte. Using the derived diffusion coefficient values, a maximum spread model using Fick’s second law was used to countercheck the maximum spread rates. In this study, we were able to derive maximum spread areas, indicating that a finite element model developed was able to replicate analyte spread at various temperature settings.","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"1 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140004623","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 system under consideration is a porous medium layer saturated with a Newtonian fluid containing gyrotactic microorganisms, and it is subjected to both gravity modulation and rotation. Through a weakly nonlinear analysis, the behavior of the system at finite amplitudes is studied. The Ginzburg-Landau equation, obtained from perturbation analysis, provides insights into the system's behavior in the presence of gravity modulation. The amplitude of convection in the unmodulated case is determined analytically, serving as a reference for comparison.\u0000The research explores the influence of various parameters on the system, including the Vadasz number, modified Rayleigh-Darcy number, Taylor number, cell eccentricity, and modulation parameters such as amplitude and frequency. By varying these parameters, the heat transfer, quantified by the Nusselt number, is analyzed and compared in different cases. The modulation amplitude is found to have a significant effect on enhancing heat transfer, while the modulation frequency has a diminishing effect.","PeriodicalId":50082,"journal":{"name":"Journal of Porous Media","volume":"2 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139926969","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}
