Abstract

The current paper deals with studying the physical characteristics of blood flow through a curved catheterized diseased artery with heat and mass transfer. The constitutive equations for incompressible and steady non-Newtonian Jeffrey fluid have been modelled and solved using the corresponding boundary conditions under the mild stenosis approximation to obtain analytical solutions for axial velocity, temperature and concentration. It is observed that, by increasing the curvature parameter, the blood velocity, the arterial wall shear stress and the temperature increase while the resistance to blood flow and concentration decrease. Besides, the values of blood velocity, arterial wall shear stress, and temperature are higher for Jeffrey fluid than for Newtonian fluid, while the inverse effect is observed for the resistance to blood flow and concentration. Moreover, the trapping phenomenon depicts that the symmetry of the trapped bolus destroys due to the curvature of the artery.
