This article investigates the heat transfer characteristics of magnetohydrodynamics water-base silver and iron oxide hybrid nanomaterials flow in a Darcy-Forchheimer porous medium induced by a stretching/shrinking surface. The results show that there are two solutions for the stretching/shrinking parameter, with the first solution being stable and physically acceptable and the second one being unstable and physically infeasible. Moreover, the skin friction and heat transfer are affected by the mass transfer parameter and the volume fraction of solid nanoparticles.
This article explores heat transfer characteristics of magnetohydrodynamics water-base silver (Ag) and iron oxide (Fe3O4) hybrid nanomaterials flow in a Darcy-Forchheimer porous medium induced by a stretching/shrinking surface with impacts of heat sink/source. Moreover, thermal radiation effects and the slip boundary conditions are also incorporated in the given problem. Governing partial differential equations (PDEs) are first altered into the ordinary differential equations (ODEs) using suitable similarity transformations. These achieved ODEs are solved by the well-known shooting technique in Maple software to get the required numerical solutions for the variation in different physical parameters. Here, the numerical findings show duality in solutions in case of stretching/shrinking parameter over different ranges of the comprised distinguished parameters. In this regard, the stability analysis is done and the first solution is found stable and physically acceptable, while the second one unstable and physically infeasible. Besides, the skin friction increases for the case of shrinking but it decreases for case of stretching parameter due to the greater impacts of the mass transfer parameter while the heat transfer phenomenon upsurges for the case of shrinking parameter. Moreover, the skin friction, and the heat transfer rise with variation of the suction parameters when the quantity of solid nanoparticles volume fraction is increased.
