This research article aims to disclose the features of nanofluidic flow manifested with Cattaneo-Christov model of heat and mass flux over non-linearly stretching surface. An incompressible visco-elastic nanofluid saturates the given porous medium through Darcy-Forchheimer relation. A non-uniformly induced magnetic effect is considered to accentuate the electro-magnetic and thermal conductivity of the base fluid. The model is restricted to small magnetic Reynolds. Boundary layer assumptions are incorporated for the given flow model. Governing equations are remodeled into non-linear ordinary differential equations through transformations. So formulated nonlinear system is solved through homotopy analysis method (HAM) to achieve series solutions for velocity field, concentration of nanoparticles and temperature distribution. It is noticed that the temperature distribution and corresponding thermal boundary layer pattern shows declination for Cattaneo-Christov model of heat and mass flux as compared to classical Fourier’s law of heat flux/conduction. Furthermore, the intensive resistance offered by the addition of porosity factor in the flow model results in rise of temperature profile, however, opposite behavior is noticed in concentration of nanoparticles. The wall-drag intensity, the heat flux and the mass flux are discussed on the premise of numerical information obtained upon simulation of the problem.

“…Hamilton and Crosser model 49 is used for the effective thermal conductivity of nanofluid as bellow:

\frac{k_{nf}}{k_{f}} = \frac{k_{normalp} + (m - 1) k_{normalf} - (m - 1) φ false(k_{normalf} - k_{normalp} false)}{k_{normalp} + (m - 1) k_{normalf} + φ false(k_{normalf} - k_{normalp} false)} .

where m is the shape factor of the nanoparticles.…”

This study aims to study numerically the free convection and thermal radiation of an Ag‐water nanofluid inside an L‐shaped inclined microelectronic module under inclined Lorentz forces and uniform heat generation/absorption effects. The study is established using the software COMSOL Multiphysics based on the finite element method. The main results obtained show that convection heat flow enhances by increasing the Rayleigh number, radiation parameter and nanoparticles shape factor, however, it reduces with increasing the Hartmann number and the aspect ratio. In addition, the presence of uniform heat absorption improves the convection heat flow, by contrast, the presence of uniform heat generation damages this. Besides this, the Lorentz forces' directional impact on the convection heat flow is linked to module inclination. The average Nusselt reaches a maximum for module inclination γ = 45 °.

In this study, the natural convection of a magnetohydrodynamic nanofluid in an enclosure under the effects of thermal radiation and the shape factor of nanoparticles was analyzed numerically using the control-volume-based finite element method (CVFEM). Columns, spheres, and lamina are examples of the nanoparticle shapes used in the investigation. The study of nanofluid flow and heat transfer was accomplished with an extensive range of nanofluid volume fractions, radiation parameters, Hartmann numbers, Rayleigh numbers, and nanoparticle shape factors. Also, the correlation between the average Nusselt number and the influencing parameters of the current study was determined. The findings demonstrate that laminar nanoparticles have a more notable impact on the average and local Nusselt numbers than the other nanoparticle shapes.
