Numerical Simulation of Heat Transfer in MHD Hybrid Blood Nanofluid Flow through a Bifurcated Stenosed Artery

Abstract:

Atherosclerosis occurs due to plaque thickening in arteries, reducing blood flow and oxygen supply to tissues. This study models blood flow in a bifurcated stenosed artery under a uniform magnetic field, analyzing magnetohydrodynamics (MHD) hybrid blood nanofluid flow with heat transfer. Using COMSOL Multiphysics, the laminar and Newtonian flow of a hybrid blood nanofluid with silver (Ag) and gold (Au) nanoparticles is simulated. Results, validated by existing literature, highlight key parameters such as velocity, heat flux, and wall shear stress (WSS). The study shows that Ag and Au nanoparticles improve blood flow, reducing recirculation in stenosed arteries, offering the potential for nanomedicine treatments.
