Abstract

This study aims to investigate heat transfer and entropy generation for a non-Newtonian power-law fluid in an asymmetrically heated parallel plate channel. By employing the stress and straining rate relationship for a power-law fluid, and accounting for viscous dissipation, this work presents an analytical model that integrates the effects of power-law rheology, and asymmetrical heating conditions, yielding expeditious closed-form temperature and Nu expression. The heat transfer and entropy generation are elucidated for the internal forced convection of a shear-thinning hybrid nanofluid, specifically, multiwalled carbon nanotubes (MWCNTs)–SiO2/EG–water, with known rheological behavior in the literature, in an asymmetrically heated microchannel for a Reynolds number,
