Abstract: Abstract Recent advancements in nanotechnology have highlighted the increasing application of nanofluids in biomedical and hematological treatments. In this study, the nonlinear characteristics of blood flow containing silver nanoparticles are theoretically examined under the influence of an external force field, where water serves as the base fluid in an inclined arterial segment with composite stenosis. A suitable mathematical formulation is employed to describe the geometry of the composite stenosed artery, and the governing coupled partial differential equations are developed to analyze the rheological behavior of the flow. Using the mild stenosis approximation together with appropriate boundary conditions, analytical solutions are obtained for velocity distribution, temperature field, wall shear stress, and flow resistance. Numerical simulations are carried out and the results are illustrated graphically to demonstrate the effects of stenosis severity, arterial wall elasticity, and silver nanoparticles on blood flow characteristics. The analysis reveals that the inclusion of silver nanoparticles significantly enhances hemodynamic performance and improves circulation in diseased arteries, while an increase in stenosis height leads to greater wall shear stress and higher resistance to flow. These findings may provide useful insights for medical researchers and clinicians in understanding blood flow behavior in stenosed arteries.
