This paper explores the consolidation power of different nanomaterials in a hybrid material, focusing on metallic and metallic-oxides nanoparticles. A developed MHD-hybrid model for a thermal energy system with seven types of nanoparticles is analyzed, with emphasis on the morphology and size factor of each nanoparticle. The research investigates the effect of morphology of metallic and non-metallic nanoparticles on flow and heat transfer rate in hybrid nanofluids.
The consolidation power of different nanomaterials such as metallic nanoparticles and metallic-oxides nanoparticles in a new-fangled and energetic hybrid material should give rise to fascinating properties that combine the advantages of each of the nanocomponents. In this paper, developed an MHD-hybrid model for the thermal energy system with seven different types of nanoparticles. For this purpose, we simulate the thermal conductivity and viscosity hybridized nanocomponents modeled based on the shape and size factor of each nanoparticle. The effect of morphology for Metallic and non-Metallic nanoparticles on flow and heat transfer rate has been investigated through hybrid nanofluids flow. Mathematical modeling of the concerning problem is done in the form of the partial differential structure under the boundary layer theory. The intrinsic features of capitalized induced particles along with base fluid are presented by empirical relations and utilized during the formulation of work. These hybrid nanofluids flow passing through the two orthogonal moving up/down porous disks. Thermal enhancement performance is analyzed through variation of shape and size of the nanoparticles with convective conditions. A stable system of nonlinear differential equations is obtained by applying suitable transformation on governing partial differential equations. Consequences of pertinent parameters on axial velocity, radial velocity, tangential velocity, and temperature distribution are elaborated. Important results of non-dimensional parameters with different types of hybrid nanofluids are examined through porous orthogonal disks. We achieved that the carbon nanomaterial has significant results on thermal performance. Novel results are obtained on thermal conductivity and viscosity associated with the shape/size of the nanoparticles. Shear stress increases with the increase of values of MHD. For the injection case, the Nusselt number shows significant results. If we increase the size of the nanoparticles then Skin friction also increases. This research set a strong foundation in the field of nano-biomedical devices, and engineering nanotechnology oriented electronic computers.
