چکیده (انگلیسی):

Solution of blood flow problem in a tapered artery is presented in this paper. Where blood is taken as non – Newtonian Casson’s fluid. The effect of various parameter of blood flow with respect to tapered angle have been studied. Analytical expression for velocity, wall shear stress and volumetric flow rate is given in this paper. The graphical representations have been made to validate the analytical findings with a view of its applicability to stenotic diseases. It is found that wall shear stress increases when peak is obtained then decreases for different values of tapering angle.
