Numerical evaluation of Darcy Forchhemier hybrid nanofluid flow under the consequences of activation energy and second-order chemical reaction over a slender stretching sheet

The flow characteristics of mixed convection, electrically conducting Darcy Forchhemier hybrid nanofluid across a permeable slender stretching sheet have been reported. The significances of variable magnetic fields, zero mass flux, second-order chemical reaction, heat source, activation energy, and Hall current are all also considered in the present analysis. In the working fluid, titanium dioxide and cobalt ferrite nanoparticles are added to water for the formation of a hybrid nanofluid (HNF). TiO2 and CoFe2O4 nanoparticles are inorganic compounds that have been systematically proven to have wide-ranging industrial applications. The proposed model has been presented as a system of partial differential equations. By using similarity substitutions, the system of PDEs is simplified to the system of ODEs. The obtained set of differential equations is further evaluated by using the computational approach 'Parametric Continuation Method' (PCM). The results are verified for consistency and validity purposes with the available study and the bvp4c technique. The thermal energy profile is amplified with the rising values of Hall effect. Furthermore, the mass transfer rate of hybrid nanofluid rises with the impact of the activation energy and chemical reaction.
