Magnetized homann flow comprising GO and Co3O4 nanoparticles past a biaxially stretching surface

Abstract

The usage of hybrid nanofluid due to their outstanding thermal conductivity has become a fascinating topic in research. This study considers the suspension of graphene oxide and cobalt oxide in ethylene glycol on a biaxially, planarly, and perpendicularly stretching surface. The influence of heat Cattaneo-Christov double diffusion with generation/absorption, Joule heating, and shapes of nanoparticles is scrutinized. The similarity conversions are assumed, which determine dimensionless ordinary equations. The collocation method, bvp4c routine is utilized to determine the numerical and asymptotic behavior of the problem. Because of better thermal and electrical conductivity of nanoparticles under consideration, this research can be used for energy storage, electronics, catalytic supports, and cooling of a system. The thermophysical properties are scrutinized via the Hamilton-Crosser model of nanofluids, which is significant as it provides a quantitative understanding of the heat transfer behavior of nanofluids, enabling the design and optimization of nanofluid-based heat transfer systems. Due to the magnetic field, temperature distribution is increased; however, velocities diminish. Moreover, energy transport is maximum for spherical-shaped nanoparticles, while it is lowest for blade-shaped nanoparticles. By incrementing volume fraction, the intermolecular motion amongst the particles becomes disorderly and erratic, which enhances the flow and thermal transport. The wall stress parameter along the x-axis is augmented due to an increment in the stretching parameter, while the opposite trend is seen for the wall stress parameter along the y-axis.
