摘要

This study investigates the thermal transport of the distinctive behavior of fluid flow under magnetohydrodynamics (MHD) micropolar hybrid nanofluid flow over a permeable stretching cylinder. The mathematical model integrates key physical mechanisms, including micropolar fluid, MHD, porous medium, thermal radiation and heat generation or absorption. The set of partial differential equations (PDEs) are reduced to a set of ordinary differential equations (ODEs) through suitable similarity transformations, which are solved numerically using a Bvp5c method in MATLAB software. The findings highlight the coupled influence of magnetic, porosity, thermal radiation, heat source/sink and micropolar parameters on velocity and temperature profiles. The consistency and reliability of the numerical results are checked by conducting a thorough investigation of grid independence and convergence. The present analysis reveals that increases the magnetic parameter values decreases the velocity profile due to Lorentz drag force, while enhances temperature profile. Increasing micropolar parameter values increase the velocity profile and declines temperature profile. The thermal radiation and heat generation parameter values increase significantly enhance temperature profiles. Comparative analysis shows that the Cu–Al2O3/blood mixed nanofluid displays higher thermal improvement compared with Ag–MgO/blood due to its stronger effective heat conductivity characteristics. The present study applied in various applications like controlled hyperthermia treatment techniques, magnetic delivery of medications, biological-nanofluidic transport technologies, and sophisticated thermal control applications incorporating blood-based mixed nanofluids.
