摘要

This study examines entropy generation in the context of magnetohydrodynamic peristaltic electro-osmotic flows of Jeffrey blood based hybrid nanofluid containing gold (Au) and titanium dioxide (TiO2) nanoparticles through a non-uniform channel. The primary objective is to analyze the influence of various physical parameters on velocity, heat transfer, concentration of hybrid nanofluid flow, as well as entropy generation. The governing equations for motion, heat transfer and nanoparticle dynamics, which are nonlinear coupled differential equations, are solved using the Homotopy Analysis Method (HAM). The analysis presents a comprehensive mathematical and graphical investigation of how the key parameters influence temperature and concentration profiles. These parameters include couple stress, magnetohydrodynamic (MHD) effects, the Brownian motion parameter, the thermal Grashof number, the thermophoresis parameter, and density Grashof number. The electromagnetic forces and nanoparticle interactions critically influence hybrid nanofluid dynamics. The magnetic and thermophoresis effects enhance temperature fields and decrease velocity due to increased viscosity. Entropy increases with key parameters, but the domination of flow entropy drops the Bejan number, emphasizing the system’s shift toward viscous dissipation-driven inefficiencies. These intuitions are dynamic for optimizing thermal systems using hybrid nanofluids.
