Краткое описание

This paper presents the detailed numerical study of blood flow through models of stenotic and tapered arterial segments. The arterial model is treated to be two-dimensional and axisymmetric. A tapered artery with an overlapping stenosis is considered here in order to update the resemblance to the in vivo situation. The blood flowing through the artery is treated to be Newtonian. To compute the flow characteristics, such as wall pressure, flow velocity, and wall shear stress, the unsteady Navier-Stokes equations are solved numerically by using the marker and cell method. Finally, the numerical illustrations presented in this paper provide an effective measure to estimate the combined influence of tapering and stenosis on the flow characteristics.
