Mathematical Analysis of Hybrid Nanoparticles (Au−Al2O3) on MHD Blood Flow Through a Curved Artery with Stenosis and Aneurysm Using Hematocrit-Dependent Viscosity

Abstract

The current study deals with hybrid nanoparticles (Au−Al2O3/blood) to explore the impact of hemodynamic parameters (such as wall shear stress and resistive impedance) on unsteady MHD blood flow via a curved artery in the presence of stenosis and aneurysm. The governing momentum equation is solved using the Crank-Nicolson method. Velocity contours for numerous parameters have been provided to study the overall behavior of flow patterns. Comprehensive solutions for gold and gold-aluminum oxide hybrid blood flow are presented using medically relevant hemodynamic data. The investigation shows that hybrid nanoparticles (Au−Al2O3) have lower hemodynamic characteristics such as WSS (wall shear stress) and resistive impedance. The findings could aid in identifying and treating cancer, plaque rupture, the clearance of blood clots, infections, and brain aneurysms.
