Abstract
As the leading cause of death worldwide, cardiovascular disease underscores the urgent need for effective therapies and diagnostic tools. The use of magnetic fields and nanoparticles has demonstrated potential for creating cutting-edge treatments. To analyse blood flow in an artery with stenosis and the impact of an external magnetic field on blood flow infused with hybrid nanoparticles, this study is conducted. A generalised power law is used to model the flow of a hybrid blood nanofluid comprising silver (Ag) and gold (Au) nanoparticles. This study focuses on a deeper level of the magnetic field with hybrid nanoparticles in a non-Newtonian fluid, which extends from previous studies on nanoparticles in Newtonian blood. In a straight artery, the blood flow through a cosine-shaped stenosis is simulated using COMSOL Multiphysics software. The physical controlling parameters, including velocity profiles and wall shear stress, are illustrated through graphs. The external magnetic field significantly reduces shear stress and the velocity profile. The addition of gold and silver nanoparticles allows for smooth blood flow in the diseased artery. The findings show a decline in aberrant behaviour and recirculation in the post-stenotic area. The combination of a hybrid nanofluid with an external magnetic field presents a practicable method for improving blood flow in stenosed arteries. The results have implications for targeted drug delivery in stenotic arteries and advancements in nanomedicine.
