摘要

This study investigates the flow and heat transfer characteristics of magnetohydrodynamics (MHD) blood hybrid nanofluid flow through an inflamed stenosed artery, motivated by the need to understand cardiovascular disease mechanisms and enhance biomedical applications. Gold and silver nanoparticles are added to the base blood due to their potential in targeted drug delivery and imaging. This problem provides a prospective model for studying blood flow through stenosed arteries. The finite element method FEM is used to solve dimensionless governing equations. The stream function and isotherms contours represent the flow pattern and temperature distribution, respectively. The findings reveal that the size of the vortices is seen to decrease due to the changing position of the upper stenosis, whereas it rises with increasing stenosis. As stenosis increases, the Nusselt numbers at the upper and lower walls are observed to be intense. The magnitude of vertices and isothermal patterns is enhanced by increasing the value volume fraction \(\phi\) ϕ , whereas it decreases by increasing the Hartmann number \(Ha\) Ha . The average Nusselt number has a direct relation with volume fraction \(\phi\) ϕ inverse relation with Hartmann number \(Ha\) Ha . The novelty lies in integrating the effects of inflamed stenosis, MHD, and hybrid nanofluids for the first time to predict thermal enhancement mechanisms, offering deeper insights into heat transfer optimization in biomedical applications.
