Effect of Variable Viscosity Due to Graphene Oxide Nanofluid Flow in an Inclined Channel

Studying the nanofluid flow with consideration of variable thermophysical properties is important for the effective utilization of these properties for industrial applications. Particularly, in inclined channels, the nanofluid flow has wide applications including medicine such as the stenosis treatment. This investigation is one such computational report which considers the varying properties of the fluid flow between two inclined plates due to graphene oxide nanofluids. The flow is modelled including the impacts of Soret and Dufour effect and thermophoretic diffusion and Brownian motion. Spectral method is used to solve the complex nonlinear equations under convective conditions. The influence of implanted effects on skin friction, and entropy of the nanofluid are studied. From the results, it is interpreted that mass transfer is improved by improving the heat flux due to mass gradients and heat transfer accounts for the energy loss as entropy. A comparison table between literature and the obtained values shows good agreement. Also, the results obtained are graphed and discussed in detail along with entropy generation.
