Electrothermal analysis for reactive Powell Eyring nanofluid flow regulated by peristaltic pumping with mass transfer

Abstract

The proposed work presents an optimized thermal frame for electroosmosis optimized peristaltic transportation of reactive Powell-Eyring magneto-nanofluid with mass transfer. The peristaltic phenomenon with the applications of electro-kinetic pumping develops the effectiveness of smart pumps in nanotechnologies and medical uses. The thermal and mass characteristics of a nanofluid is obtained by evaluating the well-known Buongiorno model, which allows us to identify appealing aspects of thermophoretic diffusion and Brownian motion. The non-Newtonian nanofluid flows through a porous space under the influence of variable thermal conductivity, chemical reactions, magnetic field, and mixed convection. Zero mass flux at the channel borders are taken. A biological estimate of the creeping transportation model, long wavelength assumptions, and Debye-Hückel linearization is revealed. The resulting equations are then resolved numerically, and the results obtained are discussed in detail along with their graphical representation. The investigation reports that electroosmotic and Joule heating parameters significantly improve the temperature of Powell Eyring nanofluid. The total entropy (irreversibility rate) of the system can be controlled with the thermal conductivity parameter in the case of auxiliary pumping. A development in concentration profile is seen for greater chemical reaction parameters. Further, nanofluid flow declines with higher values of electroosmotic velocity and the Powell-Eyring fluid parameter.
