Effects of stenosis and thrombosis on skin friction in arteries

The graphs of skin friction with axial distance z are shown in Figs. 7a – 7b for several values of parameters (a) ζ and (b) δ, with R = 1, b = 1, a = 0, m = 2, β = 0.5 and Gr = 5. It is observed that the arterial wall experiences higher stress when stenosis grows deeper and in addition to the thrombosis growth. This further influence the wall shear stress to surge significantly which leads to the declining of blood movement in the artery.
