Parametric simulation of hybrid nanofluid flow consisting of cobalt ferrite nanoparticles with second-order slip and variable viscosity over an extending surface

Abstract This study explores the unsteady hybrid nanofluid (NF) flow consisting of cobalt ferrite (CoFe 2 O 4 ) and copper (Cu) nano particulates with natural convection due to an expanding surface implanted in a porous medium. The Cu CoFe nanoparticles (NPs) are added base fluid water synthesize NF. effects second-order velocity slip condition, chemical reaction, heat absorption/generation, temperature-dependent viscosity, Darcy Forchheimer also assessed present analysis. An ordinary differential equation system is substituted for modeled equations problem. Further computational processing performed using parametric continuation method. A validation accuracy comparison Matlab package BVP4C. Physical constraints used presenting reviewing outcomes. With increase condition rates mass transition significantly variation Fe NPs. findings suggest that uses fluids might be useful aerodynamic extrusion plastic sheets polymer sheet from dye.
