Abstract

In the present work, flow of a pulsatile Casson fluid through a stenosed artery has been investigated. The artery is assumed to be a cylinder of finite length and uniform diameter. Stenoses are considered to be present on inner side of the artery wall. Artery wall is assumed to be elastic in nature. The governing momentum equation is expressed in terms of the shear stress. The momentum equation along with the initial and boundary conditions are solved numerically. Finite element analysis is employed and artery wall displacements are computed. The fluid solid interaction (FSI) and convergence study is carried out. Influence of (i) the radial displacement of artery wall (ii) the location of the stenosis, (iii) the height of the stenosis and (iv) the magnitude of artery wall elastic coefficients on the radila deformation and the wall shear stress have been investigated.
