Effects of Stenosis on Non-newtonian Flow of Blood in Blood Vessels

An attempt has been made to investigate the wall shear stress, resistance parameter and flow rate across mild stenosis situated symmetrically on steady blood flow through blood vessels with uniform or non-uniform cross-section by assuming the blood to be Non-Newtonian, incompressible and homogeneous fluid. An analytic solution for Power law Fluid, Bingham Plastic fluid, Casson Fluid has been obtained. For the physiological insight of the problem various parameters of systemic and pulmonary artery are taken and the study reveals that as the height of the stenosis increases in blood vessels, the shear stress and resistance parameter steadily increases, whereas, flow rate decreases steadily
