Blood flow model is consider to study the influence of magnetic field and different shaped nanoparticles in non-tapered stenosed arteries. The metallic different shaped nanoparticles for the blood flow with water as base fluid is not explored so far. The representation for the blood flow is through an axially and radially symmetric stenosis. Symmetry of the distribution of the wall shearing stress and resistive impedance and their growth with the developing stenosis is another important feature of our analysis. Exact solutions have been evaluated for velocity, resistance impedance, wall shear stress and shearing stress at the stenosis throat. The graphical results of different type of tapered arteries (i.e., converging tapering) have been examined for different parameters of interest for Cu-water.
