Significance of Activation Energy in Eyring-Powell Nanofluid Flow Exposed to Inclined Magnetic Field: Entropy Analysis

Abstract

In the present report, we explore the highlights of activation energy and first-order chemical reaction on the Eyring-Powell nanofluid flow in an upstanding channel with the imposed inclined magnetic field along with the heat generation/absorption. The equations regulating the flow are modelled using Buongiorno model by incorporating the brownian movement and thermophoresis effects of nanofluids. No slip and convective conditions are applied on velocity and temperature respectively at the boundaries of the channel. The governing equations are then changed to dimensionless form by defining suitable non dimensional physical variables. The system of coupled differential equations is solved using bvp4c MATLAB code. The velocity, temperature, nanoparticle concentration and entropy generation are analyzed through graphs and flow rate, heat and mass transfer rate are analyzed through tabular values for a scale of values of various physical variables. It can be reported that entropy generation can be minimized by incrementing the fluid parameter and the strength of imposed magnetic field.
