The mechanical properties of functionally graded plates, such as their elasticity modulus and density, are varied in accordance with the power law, while the constant Poisson's ratio is taken into consideration, and porosity is assumed to be classified into two categories: evenly and unevenly distributed. On the basis of first-order shear deformation theory and Hamilton's principle, the theoretical equations of motion and boundary conditions are obtained. The concepts of change of variables, as well as the implementation of the generalized differential quadrature method and the Newmark procedure, have all been used to achieve dimensionless discrete equations. The effects of the volume fraction index, the velocity of the load, the porosity volume fraction and distribution pattern, the boundary conditions, the modulus of the Winkler foundation, and the Pasternak shear layer foundations' stiffness on the displacements and stresses of plates have been investigated.","PeriodicalId":45135,"journal":{"name":"Special Topics & Reviews in Porous Media-An International Journal","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135556526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis is carried out using linear stability theory, normal mode technique, and one term Galerkin type weighted residual method for various metallic and non-metallic nanoparticles. The outcomes are compared with previously published results, and fine agreements are noted for the permissible range of parameters. Numerical simulation for porous media is carried out for blood (Casson fluid) using the software Mathematica to make the investigation helpful for practical applications. The effect of porous medium, rotation, Casson parameter, and nanoparticle parameters is discussed. Interestingly, it is found that though Casson fluids are more stable as compared to regular fluids, the Casson parameter itself has a destabilizing effect on the system. The main objective of the study is to consider the impact of Coriolis force on a Casson nanofluid layer with metallic and non-metallic nanoparticles. This effect is of paramount importance in geophysical studies, particularly in the extraction of crude oils. Further, by increasing the rotation parameter, the axial velocity of the blood-based Casson fluid increases, which may help in the treatment of stenosis of arteries and throat. The importance and novelty of the study is the fact that Coriolis force can stabilize various nanoparticle-based Casson fluid layer systems, which were otherwise unstable. As far as metallic and non-metallic nanoparticles are concerned, the stability pattern followed by metallic nanofluids is iron-blood > copper-blood > silver-blood > gold-blood, and for non-metallic nanofluids is silica-blood > alumina-blood > titanium oxide-blood > copper oxide-blood.","PeriodicalId":45135,"journal":{"name":"Special Topics & Reviews in Porous Media-An International Journal","volume":"27 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74564284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The so-called Darcy-Brinkman model for the top-heavy distribution of nanoparticles has been employed. A three-temperature local thermal non-equilibrium (LTNE) model, assuming one-temperature field for the solid matrix, one for the base fluid, and one for the suspended nanosized particles, is employed, incorporating the effects of Brownian and thermophoretic diffusions. Numerical computations are carried out with the software Mathematica (version 12.0). The novelty of the problem lies in the fact that destabilizing influence of nanoparticles and solute is countered with stabilization due to the presence of Darcy-Brinkman porous medium. Further, it has been observed that the two LTNE parameters namely, Nield parameter for particles and modified solute thermal capacity ratio, have destabilizing effects which are balanced by the other two parameters, viz. Nield parameter for solute and modified thermal capacity ratio for particles. The impact of nanofluid parameters is found to destabilize this top-heavy configuration of nanoparticles. Due to the consideration of Darcy-Brinkman model, Darcy number came into existence, which postpones the onset of instability. Similar is the effect of porosity and modified thermal diffusivity ratios for the particles as well as the solute.","PeriodicalId":45135,"journal":{"name":"Special Topics & Reviews in Porous Media-An International Journal","volume":"92 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76384697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
