AB - The aim of this paper is to deal with the pulsatile flow of blood in stenosed  arteries using one of the known constitutive models that describe the  viscoelasticity of blood witch is the generalized Oldroyd-B model with a  variable-order fractional derivative. Numerical approximation for the axial  velocity and wall shear stress were obtained by use of the implicit  finite-difference scheme. The velocity profile is analyzed by graphical  illustrations. This mathematical model gives more realistic results that will  help medical practitioners and it has direct applications in the treatment of  cardiovascular diseases.
