Irreversibility scrutiny of chemically reactive Powell–Eyring liquid flow in a microchannel with Buongiorno model: a hybrid nanoparticles aspect

Abstract

Hybrid nanoliquids are a miscellany inventive magnificence of nanoliquid that have been used in the province of thermal transfer such as microfluidics, protection, naval, and acoustics. Hence the main theme of the current work is to elucidate the mass and thermal behaviour of Powell-Eyring fluid flowing through an upright microchannel along with irreversibility analysis and to scrutinize the outcome of non-linear thermal radiation. The ethylene glycol and water are the base fluid with Fe₃O₄ − Ag nanoparticles have been considered. Chemical reactions and buoyant forces are deliberated in the study. Brownian motion, thermal dependent heat source, and thermophoresis impact were considered. Convective and slip conditions are taken at the boundaries of the channel. The governing equations were solved numerically by using Runge-Kutta Fehlberg’s fourth-fifth order. The exploration of this study upholds the amplification of solutal the Grashof number amplifying the velocity field. A significant decrement was noticed in entropy with an inflated Powell-Eyring-fluid parameter. The concentration field of the fluid flow is enhanced with the improved Schmidt number. The outturn therein established that the rate of thermal transfer in Fe₃O₄ −Ag/EG based hybrid nanoliquid is more remarkable when compared to Fe₃O₄ −Ag/water based hybrid nanoliquid.
