Abstract
In the present article, the blood flow through a tapered artery with a stenosis is analyzed by considering axially nonsymmetric but radially symmetric mild stenosis on blood flow characteristics in the presence of heat and mass transfer, assuming the flow is steady and blood is treated as hyperbolic tangent fluid. The solution of the nonlinear equations have been obtained by employing a regular perturbation technique. Perturbation solutions have been evaluated for velocity, temperature, concentration, resistive impedance, wall shear stress, and shearing stress at the stenosis throat. The quantitative behavior of the power law index m, Weissenberg number We, stenosis shape n, Brinkman number B sub(r, Soret number S) sub(r) and maximum height of the stenosis delta for different types of tapered arteries (i.e., converging tapering, diverging tapering, nontapered artery) has been examined through graphs.
