Slip examination on the wall of tapered stenosed artery with emerging application of nanoparticles

In this analysis, slip effects on the wall of a tapered stenosed artery has been considered under the mild stenosis approximation. The theoretical analysis is carried out by considering blood as Newtonian fluid. An exact solution of temperature and velocity profile is obtained by solving the governing equations after using non dimensional parameters. Hemodynamic effects of stenosis are discussed through the graphs of resistance impedance to blood flow and wall shear stress. The examination shows that the addition of silver nanoparticles reduces the resistance impedance more effectively as comparing to the copper nanoparticles. The trapping pattern also shows that the impulsion of nanoparticles speed up blood flow in the stenotic region. This effect is noticeable and shows that this model could be helpful in some biomedical application. (C) 2016 Elsevier Masson SAS. All rights reserved.
