Abstract
In this article we have examined the blood flow of Jeffrey nano fluid model with stenosis. The effects of heat transfer and nanoparticle fraction are taken into account. The tube is taken vertically upward, so the gravitational effects are also considered. After using the non-dimensional variables, the analytical solution of the resulting equations have been found with the help of homotopy perturbation method and Adomion decomposition method. The physical features have been discussed through graphs of velocity profile w, nano concentration profile sigma, resistance impedance lambda, wall shear stress S-rz, temperature profile theta, wall shear stress at the stenosis throat tau(st) and stream lines. The comparison of both the analytical solution are also presented.
