Abstract
The present study investigates the behavior of blood flow in a stenosed human artery in the presence of gold (Au) nanoparticles (NPs). The governing equations describing the hemodynamic flow characteristics are discretized using a finite difference scheme to ensure accurate numerical representation of the system. These discretized equations are subsequently solved and simulated using MATLAB software to analyze the flow dynamics. The study focuses on evaluating key hemodynamic parameters, including axial velocity profiles, volumetric flow rate, and resistive impedance, both in the absence and presence of gold nanoparticles. The inclusion of Au nanoparticles is observed to cause notable alterations in these parameters, indicating a reduction in flow resistance and enhancement in flow uniformity. Such improvements suggest that nanoparticle-assisted blood flow modulation could play a beneficial role in developing advanced therapeutic strategies for cardiovascular diseases and the management of arterial stenosis.
