Influence of thermal stratification and thermal radiation on graphene oxide-Ag/H2O hybrid nanofluid

In this article, the behavior of MHD hybrid nanofluid passing through a stretching sheet is examined. The current consideration also flashes the thermal radiation effects on hybrid nanofluid. Hybrid nanofluid is the new class of nanofluids which is very famous nowadays. Graphene oxide and silver as nanoparticles and water as a host fluid are considered. We presume low magnetic Reynolds number, and the magnetic field is enforced in the vertical direction. Features of heat transfer are assessed first time by exploiting the graphene oxide-Ag/H2O hybrid nanofluid with thermal radiation. By utilizing suitable transformations, governing equations are incorporated for heat and flow. Corresponding ordinary differential equations are solved by the homotopic procedure. The disparity of unlike parameters on flow and heat is revealed graphically. Resistive force is incorporated mathematically. The nanoparticle volume fraction of graphene oxide enhances both the velocity and temperature of the fluid. It is noticed that the thermal stratification parameter decays the temperature field while the opposite trend is observed for the radiation parameter. The heat transfer rate is disclosed by 3D graphs. It is observed that the temperature profile diminishes for enhanced thermal stratification parameters. Also, the heat transfer rate diminishes for radiation number and stratification parameter.

Automated summary

This study examines the behavior of MHD hybrid nanofluid passing through a stretching sheet, with a focus on the thermal radiation effects on the nanofluid. The research reveals that the nanoparticle volume fraction of graphene oxide enhances both the velocity and temperature of the fluid. Additionally, the study shows that increasing thermal stratification parameters lead to a decrease in temperature profile, while radiation number and stratification parameter decrease the heat transfer rate.
