Influences of imposed magnetic force on treatment of hybrid nanofluid involving non-Darcy porous model

Abstract In current report, hybrid nanomaterial free convection through a permeable region was scrutinized involving magnetic force. Porosity effect is studied using non-Darcy porosity model. Hybrid nanoparticles, multiwall carbon nanotubes (MWCNT) and Ferrous Ferric Oxide (Fe3O4), are merged into pure water (H2O) to compose working nanofluid. Moreover, effects of radiation and various shapes nanoparticles has also been reported. The corresponding mathematical model consists of set of nonlinear partial differential equations (PDEs) including conservation of mass, momentum and energy along with specified boundary conditions. The numerical modeling is carried out via Control Volume Finite Element Method (CVFEM). The space discretization is performed using non-uniform finite number of triangular elements. Impacts of Darcy number, magnetic force, radiative and buoyancy forces on nanomaterial behavior have been displayed. Result revealed augment in Nusselt number due to augment in radiation, while converse trend is seen due to rise in Hartmann and porosity effect.
