| Summary: | This study investigates sodium alginate (SA)-based nanofluids, highlighting their thermophysical properties and potential advantages over conventional heat transfer fluids. It examines the influence of nanoparticle morphology on TiO₂, Al₂O₃-Cu nanofluids, and non-Newtonian viscoplastic SA-based fluids under a transverse magnetic field. Four nanoparticle shapes—cylinders, bricks, blades, and platelets—are considered. Nonlinear PDEs are transformed into ODEs and solved numerically using the Runge–Kutta–Fehlberg method in MAPLE. Results show that temperature decreases with a higher Prandtl number but increases with the Eckert number and viscoplastic parameter. The velocity profile decreases for all Cu nanoparticle shapes but rises with a more significant stretching surface parameter. Alumina-based nanofluids reduce viscosity without lowering thermal conductivity. These findings benefit applications in electronic cooling, biomedical hyperthermia, and manufacturing processes. |
