| Summary: | This study examines how heat generation affects blood flow containing gold nanoparticles in a porous curved channel. The fluid follows magnetized Powell-Eyring dynamics with Darcy-Forchheimer resistance, Joule heating, and variable thermal conductivity. Heat transfer is modeled using CattaneoChristov theory. The governing equations are simplified using similarity transformations and solved analytically via the Homotopy Analysis Method (HAM). Results show that: • The velocity profile declined with increased unsteadiness, magnetic field, porosity and nanoparticle concentration. • Temperature rises when more magnetite nanoparticles are added, improving blood's thermal properties. We also analyze entropy generation, bacterial density, and nutrient distribution in blood flow. Clinically, since tumors reduce blood circulation, these findings may help optimize nanoparticle-based hyperthermia treatments. |
