This communication reports the joint effects of Thermal Diffusion and Diffusion Thermo on viscous and incompressible three-dimensional nanofluid flow towards a stretching sheet in connection to the influence of a magnetic field. In this study, nanofluid model is employed for the effects of thermophoresis and Brownian motion. Following that, similarity variables are chosen to turn the dimensional nonlinear system into dimensionless expressions and the resultant transformed equations are solved numerically using Finite Element method. Special emphasis has been given to the parameters of physical interest. These findings are visually presented through graphical representations, providing a clear and insightful understanding involved in this flow scenario. In addition, the final results are examined in light of past research and it is determined that they meet the convergence standards to an exceedingly satisfactory degree. The study’s findings are beneficial for many technical and commercial endeavours.

This investigation elucidates the intertwined effects of magnetic fields and porous media on the flow of nanofluids towards a stretching sheet, contemplating variable viscosity and convective boundary conditions. A nanofluid model, incorporating the influences of thermophoresis and Brownian motion, is adopted. Via judicious transformations, the fundamental governing coupled non-linear partial differential equations are condensed, and the consequent transformed equations are numerically resolved employing the Finite Element Method (FEM). Paramount emphasis is accorded to parameters embodying notable physical significance, inclusive of the Prandtl number (P r), Hartmann number, Lewis number (Le), Brownian motion number (N b), thermophoresis number (N t), and permeability parameter. The numerical results acquired, as particular instances of the aforementioned study, are found to be congruent with previously reported findings, substantiating the accuracy and reliability of the proposed methodology. A thorough examination of the collective impact of the selected parameters on flow and heat transfer characteristics has been systematically undertaken, revealing intricate dependencies and fostering a deeper understanding of the complex phenomenon under consideration. This study, hence, paves a pathway towards bolstering the comprehension of flow mechanics in porous media under the influence of magnetic fields, contributing valuable insights to the overarching field of fluid dynamics in nano-engineering applications.

Present paper studies the thermal-diffusion and diffusion-thermo effects on Casson nanofluid flow in the presence of chemical reaction with inclined magnetic field. A similarity analysis was used to transform the system of partial differential equations, together with boundary conditions into a system of dimensionless couple ordinary differential equations. A robust spectral collocation method has been adopted to obtain the solution of the transformed flow equations with corresponding boundary conditions. The impact of various controlling parameters on dimensionless velocity, temperature and nanoparticle concentration are presented graphically and discussed. The effect of the flow pertinent parameters on skin friction, Nusselt number and Sherwood number are presented in tabular form. Finally, an increase in Prandtl number and thermophoresis parameter reduce the temperature field of the flow, while increase in Eckert number enhanced the temperature profile.
