摘要

This research examines the magnetohydrodynamic (MHD) radiative peristaltic flow of a couple-stress fluid containing a three-component hybrid nanofluid of Tio2 Al2O3 and Cu nanoparticles dispersed in blood, flowing through a symmetric channel. Driven by biomedical applications, including targeted drug delivery, thermal ablation, and hyperthermia therapy, as well as industrial cooling processes, the model incorporates realistic effects including compliant channel walls, velocity slip, viscous dissipation, Joule heating, and thermal radiation. The governing nonlinear equations are formulated, non-dimensionalized, and solved numerically under the lubrication approximation. The results demonstrate that temperature increases with Hartmann number, Brownian motion, and viscous dissipation, but decreases with radiation and thermophoretic effects. Magnetic fields are found to suppress axial velocity, whereas fluid properties and buoyancy forces enhance it. Furthermore, the size and shape of trapped boluses are shown to vary significantly with magnetic strength and nanoparticle parameters. These findings highlight the potential of ternary hybrid nanofluids for improving drug delivery efficiency, advancing microfluidic devices, and enhancing heat management in biomedical and industrial systems.
