Abstract
This study presents a novel mathematical model to investigate the thermal and flow characteristics of non-Newtonian blood, modeled as a Casson fluid, in an inclined cylindrical microchannel under the combined effects of electromagnetohydrodynamics, electroosmosis, buoyancy forces, thermal radiation, and Joule heating. This unique integration addresses a critical gap in the literature, offering new insights into blood flow dynamics for advanced medical applications, such as magnetic drug delivery and thermal radiation therapy. The governing equations, formulated in cylindrical coordinates, are non-dimensionalized and analytically solved using the homotopy perturbation method, providing precise expressions for velocity, temperature, wall shear stress, and Nusselt number. Results reveal that increasing magnetic field strength reduces velocity and temperature, while higher Casson parameters decrease velocity but elevate temperature. Notably, thermal radiation lowers blood temperature and enhances blood velocity in arteries. These findings advance the understanding of blood flow control in microchannels, with significant implications for optimizing treatments for cardiovascular diseases, tumors, and vascular blockages.
