Cilia-Mediated Electroosmotic Magnetohydrodynamic Hybrid Nanofluid Transport for Biomedical Applications: Impact of Radiation and Nanoparticle Geometry
摘要
Peristaltic and ciliary motions play an important role in physiological fluid transport. However, the combined effects of electroosmosis, an inclined magnetic field, and hybrid nanoparticles on a Casson fluid have not been sufficiently investigated in such systems. In this study, the peristaltic transport of a Casson hybrid nanofluid (Au-Fe2 O3/Blood) in a ciliary channel is analyzed, taking into account the coupled influence of electroosmosis and magnetohydrodynamics. The mathematical model incorporates the relevant physical mechanisms governing transport, and the resulting flow equations are reduced using the lubrication approximation. The simplified system is then solved analytically using the homotopy perturbation method. The results show that the inclusion of hybrid nanoparticles significantly influences the thermal behavior, while electroosmotic effects modify the flow characteristics by reducing the velocity profile. Variations in velocity and temperature are examined to understand their impact on transport efficiency, trapping phenomena, and entropy generation. The present study is theoretical; the results primarily provide insight into the underlying transport mechanisms and may serve as a reference for the design and analysis of microfluidic and biofluid transport systems.
