Nanoparticle analysis for blood flow of Prandtl fluid model with stenosis

In this article, we have discussed blood flow in the nano-Prandtl fluid flow analysis in tapered stenosed arteries. The occurrence of nanoparticle fraction and heat transfer was found. Gravitational effects were also considered because the tube was taken vertically upward. Homotopy perturbation method was used to find the analytical solution of coupled nonlinear differential equations. Physical features have been discussed through graphs of concentration profile σ, velocity profile w, resistance impedance λ, temperature profile θ, wall shear stress S r z , wall shear stress at the stenosis throat τ s , and the stream lines.
