Abstract
The effects of heat transfer on the blood flow of a Walter's B fluid through a tapered artery with a mass transfer under the assumption of mild stenosis have been studied. The problem is model in cylindrical coordinates system. The analytical solutions have been carried out using regular perturbation method by taking a as perturbation parameter. The expressions for velocity, temperature, concentration, resistance impedance, wall shear stress and shearing stress at the stenosis throat have been evaluated. The graphical results of different type of tapered arteries (i.e. converging tapering, diverging tapering, non-tapered artery) have been examined for different parameters of interest. Trapping phenomena have been discussed at the end of the article. (C) 2010 Published by Elsevier B.V. on behalf of Taiwan Institute of Chemical Engineers.
