Shape effects on 3D MHD micropolar Au-MgO/blood hybrid nanofluid with Joule Heating

Abstract

Hybrid nanofluid can be considered another nanofluid due to its thermal properties and potential utilisation in heat transfer analysis. This examination's principal objective is to introduce a correlation between conventional nanofluid and hybrid nanofluid characteristics due to micropolar theory, viscous dissipation, and the effect of Joule heating over an exponentially stretched surface by considering the convention. The governing equations are transformed into a system of nonlinear equations through an appropriate similarity transformation method. The reduced system of equations is evaluated by applying the fifth-order R-K-Fehlberg technique and the shooting process. By plotting the graphs for velocity, microrotation, and temperature distributions, examination between the nature of pure blood, MgO/blood nanofluid, and Au-MgO/blood hybrid nanofluid are analyzed and noted. Results of skin friction and Nusselt number are also presented to understand better the nature of flow and heat transmission rate in a nanofluid and hybrid nanofluid. The closing remarks of this analysis are that the rate of heat exchange is 13.8 percent is high in hybrid nanofluid compared to that of nanofluid even within sight of micropolar impacts, viscous dissipation, and convective condition. Finally, platelet size nanoparticles have a higher heat transfer rate than other nanoparticles.
