Abstract
The use of hybrid nanoparticles instead of nano solid-particles is one of the most serious tasks to improve the heat transport of fluids in drilling to recovery oil. This article is to analyze the heat transport of MHD radiative Carreau hybrid nanofluid, consisting of SiO2-Fe3O4 in an equal ratio base fluid of polyethylene glycol-H2O with heat source and a viscosity variation. The PDEs system that controls the problem was resolved by a numerical method after transformation into ODEs. [PEG+H2O/SiO2](m) and [PEG+H2O/SiO2+Fe3O4](h) thin films are fabricated by using spin coating technique with a thickener of 150 +/- 5 nm/25 degrees C. The most notable findings of this analysis include the influence of the velocity, temperature outlines, drag force factor, and local Nusselt number of different variable parameters. The results specifically determine that Delta E-g(Opt) amount declines from 4.894 eV for [PEG+H2O/SiO2](m) mono nanofluid to 1.969 eV for [PEG+H2O/SiO2+Fe3O4](h) hybrid nanofluid utilizing DFT calculations HOMO and LUMO calculation. The results decide that the [PEG+H2O/SiO2](m) is transmuted from semi-conductor to [PEG+H2O/SiO2+Fe3O4](h) as a super-conductor with adding [Fe3O4](NPs). The hybrid nanoparticles have a higher influence than nanoparticles on the velocity distributions.
