The influences of heat sources, radiation, and viscous dissipation are investigated. Also, the activation energy with binary chemical reaction and suction/injection are considered into the account. The dimensional governing equations are transmitted into non-dimensional form by similarity transformations. Further, the obtained mathematical model is solved numerically in MATLAB. The effect of physical parameters pertaining in flow regime are investigated through figures and tables. Fluid velocity enhances with the impact of magnetic field, porosity and suction parameters while the Brownian motion is significant with an improved values of heat generation and radiation, Fluid temperature declines with an upsurge values of thermal relaxation time. And Increasing thermophoresis and activation energy lead to an increase in the concentration whereas the opposite trend is seen for increasing chemical reaction. The Nussult number enhanced due to the larger values of thermal Grashof number, solutal Grashof number and Biot number whereas it declines with the escalating values of Brownian motion, thermophoresis and Eckert number. The comparison of the present results is carried out with the published results and noted a good agreement.","PeriodicalId":45135,"journal":{"name":"Special Topics & Reviews in Porous Media-An International Journal","volume":"293 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":"134981397","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 modeling of the governing equations considers heating from below, Darcy flow, and Boussinesq approximations along with the presence of gyrotactic microorganisms. The system of ordinary differential equations is obtained using linear stability analysis and the normal mode technique. The single-term Galerkin method casts the analytical solutions while the higher-order Galerkin technique is employed to compute the numerical solutions. The influence of the mechanical and the thermal anisotropy parameters along with all bioconvection parameters on the onset of thermo-bio-convection are analytically as well as numerically discussed. It is perceived that bioconvection Rayleigh-Darcy number $Rb$, the gyrotactic number $G$, and P{'e}clet number $Q$ are to fast-forward the beginning of bioconvection motion. On the other hand, thermal anisotropy produces a stable system and acts to postpone the bio-convection pattern formulation. Mechanical anisotropy is found to have a destabilizing impact on the stability of the suspension and helps in the development of bio-convection. The measure of cell eccentricity parameter $alpha$ has a dual effect on system stability and stabilizes the system if $frac{delta^2_{c}}{pi^2}>1$.","PeriodicalId":45135,"journal":{"name":"Special Topics & Reviews in Porous Media-An International Journal","volume":"26 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":"135711019","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 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":"88 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78325425","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}
