摘要

The study of nanofluid through the conical geometry in porous media has applications in multiple fields including fluid dynamics systems, aerospace, biomedical practices and industrial processes, ultimately contributing to improved efficiency, sustainability and performance in critical engineering and scientific domains. Given these significant applications, this study investigated the viscous dissipation, radiation-absorption and thermo-diffusion effects on unsteady magnetized thermogenic nanofluid flow from the slopped vertical cone with chemical reaction in porous medium by considering two different water based nanofluids with Cu and Ag nanoparticles. The modeled dimensional mathematical nonlinear PDEs with initial and boundary limits are transformed into dimensionless nonlinear PDEs through the use of non-dimensional variables and then the Galerkin finite element method (GFEM) is enforced to solve them. The computed results for velocity, temperature, concentration profiles, skin friction, and heat and mass transport rates are illustrated in both graphical and tabular formats. The magnetic field effect and inclination angle influenced to decrease the nanofluid velocity whereas the medium porosity backed to increase it. The nanofluid temperature and velocity raised by heat-source and radiation effects. The influence of thermo-diffusion prompted to increase both nanofluid velocity and concentration. An increased nanoparticles volume fraction attenuated nanofluid velocity but nanofluid temperature and concentration underwent oppositely. The skin-friction for both nanofluids raised with magnetic field, angle inclination and porosity parameters. The radiation, heat-source and radiation-absorption in the flow caused to improve the heat transfer rate for both nanofluids. Importantly, the velocity, temperature and concentration of Ag-water nanofluid were found to be higher than those of the Cu-water nanofluid. Further, the accuracy of the computational scheme is validated against the existing results, which show an excellent concordance.
