EMHD Flow of MoS 2 /GO 3D hybrid nanofluid with gyrotactic microorganisms and Cattaneo-Christov heat model

An exponentially extending surface with convective conditions is the subject of this correspondence, which describes a continuous three-dimensional radiative magnetohydrodynamic flow of a Tangent Hyperbolic hybrid nanofluid. In this work, we consider a hybrid nanofluid Molybdenum Disulphide/Graphene Oxide (MoS2/GO) based on graphene oxide and molybdenum disulphide using transformer oil as the basis liquid. Nanoparticles of graphene oxide and molybdenum disulphide exhibit exceptional physical characteristics, a low coefficient of friction, and high-quality catalytic activity. With their increased adsorption capacity and high reactivity, they also have dynamic surface area. To improve the nanofluid's heat transmission properties, these alloy mixes are treated in a conventional fluid. The Cattaneo-Christov heat mass flux model perception induces flow. To solve reduced dimensionless nonlinear ordinary differential equations, the Homotopy analysis method (HAM) based on Mathematica is used. Plots are used to discuss the important roles of numerous physical parameters that are governed by the equation of movements. Comparisons with the previously published study further validate the method's efficacy. According to the results, the hybrid nanofluid (MoS2/GO) based on molybdenum disulphide and graphene oxide has an exceptionally high heat transfer rate when compared to a typical nanofluid. In contrast to the GO/transformer oil, the MoS2/GO with transformer base fluid surprisingly shows a higher skin friction but a lower heat transfer rate. In particular, adding the titania nanoparticle results in a 4–11% drop in the heat transfer coefficient and a 7–17% rise in the skin friction coefficient.
